Developer Agreement and Policy

X Developer Agreement

Last Updated: November 14, 2023

By clicking “Accept & Subscribe”, continuing to pay the recurring subscription fee for Paid Services, and by otherwise accessing or using any Licensed Material,  you agree to the terms of our Developer Agreement. Subscriptions auto-renew until canceled, as described in the Terms. A verified phone number is required to subscribe. If you've subscribed on another platform, manage your subscription through that platform.

This X Developer Agreement (“Agreement”) is a binding legal agreement between you (referred to in this Agreement as “you”) and X (defined below) and governs your access to and use of the Licensed Material (defined below), including any Paid Services (defined below).

By accessing or using any Licensed Material (defined below), or clicking on a button to accept the terms of this Agreement or recurring subscription payment for Paid Services, you agree to be bound by the terms of the Agreement. If you do not understand the Terms, or do not accept any part of them, then you may not use or access any Licensed Material. You may not use the Licensed Material or accept this Agreement if you are not of legal age to form a binding contract with X, or if you are barred from using or receiving the Licensed Material under applicable law. To purchase and use a Paid Service you must: (i) be at least 18 years old or the age of majority as determined by the laws of the jurisdiction in which you live or (ii) have the express consent of your parent or guardian to purchase and use that Paid Service.

In any case, as stated in the Who May Use the Services section of the X Terms of Service, you must be at least 13 years old to use the "Services" as defined in the X Terms of Service. If you are accepting this Agreement or using the Licensed Material on behalf of a company, organization, government, or other legal entity, you represent and warrant that you have the authority to bind such company, organization, government, or entity to this Agreement, in which case the words “you” and “your” as used in this Agreement shall refer to such entity.

Any such use of the Licensed Material is non-commercial as described in Section III(B) of this Agreement. You may not disclose, reproduce, license, or otherwise distribute the Licensed Material (including any derivatives thereof) that you retrieve through the X API to any person or entity outside the persons within your organization necessary to perform the research, unless (i) the information is disclosed to the Digital Services Coordinator or other party specifically permitted by the DSA pursuant to the “vetted researcher” status and procedures described in Article 40, or (ii) disclosure is required by law.

V. Ownership, Betas, and Feedback

A. Ownership. Except to the extent expressly stated otherwise in the Agreement, neither party will acquire any right, title or interest in any Intellectual Property Rights owned or licensed by the other party. The Licensed Material is licensed, not sold, and X (or its licensors or X Application users, as applicable) retains and reserves all rights, including all Intellectual Property Rights, not expressly granted in this Agreement. You shall not do anything inconsistent with X’s ownership, including without limitation, challenging X’s ownership of the X Marks, challenging the validity of the licenses granted in this Agreement, or otherwise copying or exploiting the X Marks, except as specifically authorized in this Agreement. If you acquire any rights in the X Marks or any confusingly similar marks, by operation of law or otherwise, you will, at no expense to X, immediately assign those rights to X.

B. Betas. X may provide you with early access to non-generally available alphas, betas, research studies, pilots, marketing services or other programs from time to time (each, a “Beta”). Betas will be considered X Confidential Information. Your participation in any Beta is at your own risk, may be subject to additional requirements, and may assist X in research, analyzing and validating existing or prospective programs, products and/or tools.

C. Feedback. X will be free to use any feedback, comments or suggestions you provide X related to X, the Licensed Material, Betas or any other of X’s products or services (“Feedback”) in any way without any compensation or obligation to you or any third party, and Feedback will be deemed the Confidential Information of X. You hereby irrevocably assign to X all right, title, and interest to Feedback.


VI. Confidentiality. You may be given access to non-public information, software, and specifications relating to the Licensed Material (“Confidential Information”). You may use Confidential Information only as necessary in exercising your rights under this Agreement. You shall not disclose Confidential Information to any third party without X’s prior written consent. You shall protect Confidential Information from unauthorized use, access, or disclosure in the same manner that you would use to protect your own confidential information of a similar nature and in no event with less than a reasonable degree of care.


VII. Term; Subscription Fees; Payment; Suspension, and Termination. 

A. Term. The term of this Agreement will start on the earlier of the date you accept them or otherwise start accessing or using any of the Licensed Material, and will continue until you stop accessing and using the Licensed Material, unless terminated earlier as described below.

B. Subscription Terms. Paid Services provided as part of the Licensed Material are made available as a recurring subscription service that provides access to certain features, benefits, or services, as described on the Developer Site and the Payment Portal. If you purchase Paid Services, you do so by paying a subscription fee in advance on a monthly basis in accordance with the payment terms set forth below. When you subscribe to access the Paid Services via the Payment Portal, you expressly agree that you are authorizing recurring payments, and that payments will be made by the payment method you have selected until the applicable Paid Services is canceled by you or by X or the Agreement is otherwise terminated. Your subscription to the Paid Service will automatically renew monthly until canceled in accordance with this Agreement. Your payment information will be automatically processed by X’s Payment Processor (defined below) at the start of each subscription period applicable to the Paid Services. If your payment information is declined, your subscription may be canceled until you provide new payment information for the applicable Paid Services. If you provide new payment information and your payment account is successfully charged, your new subscription period will be based on the original renewal date and not the date the successful charge took place. Prices for Paid Services are subject to change from time to time. X will provide reasonable advance notice of any material change to the price of Paid Services, which notice may be provided via the Developer Site. For subscription fees, price changes will take effect at the start of the next subscription period following the date of the price change. If you do not agree with a price change, you have the right to reject the change by canceling your subscription to the applicable Paid Service prior to the price change going into effect.

C. Payment Terms. X may offer payment options that vary by Paid Service, device, operating system, geographic location, or other factors, which may be updated from time to time. These payment options may include web payments using a third party payment processor (“Payment Processor”). When you access a Paid Service, you agree: (i) to pay the price listed for the Paid Service, along with any additional amounts relating to applicable taxes, credit card fees, bank fees, foreign transaction fees, foreign exchange fees, and currency fluctuations, on a recurring basis during the applicable subscription period; and (ii) to abide by any applicable terms of service, privacy policies, or other legal agreements or restrictions (including additional age restrictions) imposed by the Payment Processor in connection with your use of a given payment method. The subscription fee will automatically be applied at the start of the renewal period for the applicable subscription period unless you cancel the Paid Services on the  Developer Site. It is your responsibility to make sure your banking, credit card, debit card, and/or other payment information is up to date, complete and accurate at all times. If you make a payment for a Paid Service through a Payment Processor, X may receive information about your transaction such as when it was made, when a subscription is set to expire or auto- renew, what platform you made the purchase on, and other information. X will not be liable for any errors made or delays by the Payment Processor, your bank, your credit card company or any payment network. All payments to X are non-refundable except as otherwise expressly provided in this Agreement or as required by law.

D. Taxes and fees. All fees exclude any and all taxes and similar fees now in force, enacted or imposed in the future on the transaction, delivery of the Licensed Material or the delivery of the X Content including any sales, use or value added taxes, goods and services tax, consumption tax, customs duties, tariffs, or similar charges. These taxes may include, but are not limited to, VAT, GST, sales tax, withholding tax, and any other applicable taxes, but exclude taxes solely based on X’s net income. You are responsible for the payment of all such taxes, duties and charges, and any related penalties and interest arising from the payment of such amounts. Depending on your location, X may be responsible for collecting and reporting information related to transaction taxes arising from your purchase of Paid Services. You grant X permission to provide your account and personal information to relevant tax authorities to fulfill our tax collection and reporting obligations. 

E. Canceling Your Subscription for Paid Services. Your subscription for Paid Services will automatically renew monthly unless you cancel your subscription at least 24 hours before the end of your current subscription period. There are no refunds or credits for any partial subscription periods, including in a situation where certain features, benefits and/or services are modified or discontinued. SUBSCRIPTION PLANS ARE PREPAID, NON-REFUNDABLE (UNLESS REQUIRED BY LAW), AND AUTOMATICALLY RENEW AT THE END OF EACH SUBSCRIPTION PERIOD UNLESS THE SUBSCRIPTION IS CANCELED FOLLOWING THE CANCELLATION PROCEDURES BELOW. You may cancel your subscription for Paid Services at any time via the Developer Site and you will no longer have access to the Paid Services (or any features or functionality thereof) at the end of your then-current subscription term. When you cancel the Paid Services, your subscription will remain active from the time you cancel until the end of your current subscription period. You will not receive a refund or credit for any remaining days in your current subscription period, unless required by law. All payments for Paid Services are final and not refundable or exchangeable, except as required by applicable law. X makes no guarantee as to the nature, quality, or value of a Paid Service or the availability or supply thereof. Refunds or credits are not provided for any unused or partially used Paid Service (for example, a partially used subscription period). All Transactions are Final, unless you have a right to withdraw pursuant to law, such as provided below

1. Withdrawal Right & Refunds for Users Living in EU or UK. When you purchase any Paid Services on subscription, you expressly agree to do so on a subscription basis and that the subscription will commence immediately on your date of purchase. If you are a consumer in an EU Member State or the UK, you agree you have fourteen (14) days after your purchase to withdraw from your contract for purchase for any reason. 

2. No Withdrawal Right for Users Living in Taiwan. When you purchase Paid Services, you do so on a subscription basis, the subscription will commence immediately on your date of purchase, and the Paid Service is fully performed once begun. If you are in Taiwan, you agree that you can cancel your subscription for any Paid Services in accordance with subsection E (Canceling Your Subscription for Paid Services) above, but that there is otherwise no right to rescind your Subscription and no refund will be issued.

F. Paid Services Are Non-Transferable between X Accounts. Each purchase of a Paid Service applies to a single X account, meaning that your purchase will apply solely to the account you were using when you purchased the Paid Service and will not apply to other accounts that you may have access to, or control over. If you have or control multiple accounts and you want access to Paid Services on each account, you must purchase the Paid Service on each account individually. You may not allow others to use your X account to access any Licensed Material that such person did not order. You may not purchase a Paid Service or use any Licensed Material if you are a person with whom U.S. persons are not permitted to have dealings pursuant to economic sanctions, including, without limitation, sanctions administered by the United States Department of the Treasury's Office of Foreign Assets Control or any other applicable sanctions authority ("Prohibited Person"). This includes, without limitation, persons located in, or a citizen of, or ordinarily resident in, the following countries and regions: Cuba, Iran, the Crimea Region of Ukraine, North Korea and Syria. You represent and warrant that you are not a Prohibited Person.

G. Restrictions and Obligations. You may only purchase and use a Paid Service or use the Licensed Material if you are legally allowed to use the Licensed Material in your country and you live in a country supported by X for the applicable Paid Service or Licensed Material. X may, in its discretion, restrict the ability to access the Licensed Material or purchase a Paid Service in certain countries. X reserves the right to modify the list of supported countries from time to time. X reserves the right to refuse Paid Services transactions or to cancel or discontinue the sale or use of a Paid Service or the use of any Licensed Material in our sole discretion. 

H. Suspension. X may suspend your use of and access to the Licensed Material immediately without notice, including (a) if X reasonably believes that (i) your use of the Licensed Material would cause damage to, or an inordinate burden upon, the Licensed Material, (ii) you have violated this Agreement, (iii) you create risk or possible legal exposure for X, (iv) X’s provision of the Licensed Material to you is no longer commercially viable; (b) for prolonged inactivity; (c) if X is requested or directed to do so by any competent court of law, regulatory authority, or law enforcement agency; or (d) for failure to pay for the Paid Services. X will not be liable for damages of any sort that result from any such suspension.

I. Termination. X may terminate this Agreement for any reason, at X’s sole discretion. Except where such early termination is the result of your breach of this Agreement, such early termination by X shall be effective at the end of the then-current subscription period. If you violate the terms of this Agreement, X may terminate this Agreement for cause immediately upon notice to you and you will not receive a prorated refund for any Paid Services. You may cancel your subscription for the Paid Services or your use of the Licensed Material on the Developer Site. Upon termination of this Agreement: (a) all licenses granted in this Agreement immediately expire and you must cease use of all Licensed Material; and (b) you shall permanently delete all Licensed Material in all forms and types of media, and copies thereof, in your possession. The parties to this Agreement will not be liable to each other for any damages resulting solely from termination of this Agreement as permitted under this Agreement.


VIII. Compliance Audit. X or a mutually agreed upon third party agent subject to obligations of confidentiality will be entitled to inspect and audit any records related to the performance of this Agreement in your control or possession upon reasonable notice to you, and at a reasonable time during normal business hours, for the purpose of verifying compliance with this Agreement and the fees payable to X for the two (2) year period preceding the audit (the “Audit Period”). X may exercise its audit right no more than once every twelve (12) months, unless it has reasonable cause for noncompliance, and such audit shall not unreasonably interfere with your business activities. You will provide your full cooperation and assistance with such audit and provide access to all Licensed Material in your possession, applicable agreements and records. Without limiting the generality of the foregoing, as part of the audit, X may request, and you agree to provide, a written report, signed by an authorized representative, listing your then-current deployment of the Licensed Material. You will pay X within thirty (30) business days after the completion of the audit the amount of any underpayment revealed by any such audit. In addition, if any such audit reveals an underpayment by you of five percent (5%) or more, then you will also reimburse X for the reasonable costs and expenses of such audit. The requirements of this Section will survive for one (1) year following the termination of this Agreement.

X, or a third-party agent subject to obligations of confidentiality, may inspect and audit any records or activity related to your access to the Licensed Material to verify compliance with this Agreement. X may exercise its audit right at any time upon notice. You shall provide your full cooperation and assistance with such audit and provide access to all Licensed Material in your possession or control, applicable agreements and records. As part of the audit, at X’s request, you shall provide a written report, signed by an authorized representative, listing your then-current deployment of the Licensed Material and X Content. The rights and requirements of this section will survive for one (1) year after termination of this Agreement.


IX. Disclaimer. 




X. Indemnification. You shall defend X against any and all proceedings, demands, claims, and suits (including without limitation product liability claims), and indemnify X from any and all liabilities, damages, and costs (including without limitation reasonable attorneys' fees) to the extent arising out of: (a) your use of the Licensed Material in any manner that is inconsistent with this Agreement; or (b) the performance, promotion, sale or distribution of your Services. If X seeks indemnification or defense from you under this section, X will promptly notify you in writing of the claim(s) brought against X for which it seeks indemnification or defense. X may assume full control of the defense of claims with legal counsel of its choice. You shall not enter into any third-party agreement that would affect the rights of X, constitute an admission of fault by X, or bind X in any manner, without the prior written consent of X. If X assumes control of the defense of such claim, X shall not settle any such claim requiring payment from you without your prior written approval.




XII. Agreement Updates. X may update or amend this Agreement or any of the Incorporated Developer Terms from time to time. You will check the Developer Site regularly for updates. X will alert you of material revisions to these terms by posting the updated terms on these sites, via a service notification, or by other suitable means (e.g., via email to an email address associated with your account). The changes will not be retroactive, and the most current version of the X Developer Agreement, available at the Developer Site, will govern your access to and use of the Licensed Material and any corresponding transactions. Your continued access or use of the Licensed Material will constitute binding acceptance of such updates and modifications.


XIII. Dispute Resolution and Class Action Waiver


1. General.  The following provisions are important with respect to the agreement between you and X regarding X’s features or products memorialized by these Terms. Subject to the provisions below, including exceptions set forth in this Section F, you and X agree to arbitrate any disputes, claims, or controversies arising out of or relating to these Terms, the marketing of the Licensed Material, and/or your participation in the Licensed Material (individually a “Dispute,” or more than one, “Disputes”).

2. Initial Dispute Resolutions. Most disputes between you and us can be resolved informally. If you’ve already purchased a Paid Service, our support team is available via the support link available in the navigation menu of the Developer Site. When you contact us, please provide a brief description of the nature and bases for your concerns, your contact information and the specific relief you seek. The parties shall use their best efforts through this support process to settle any Dispute. You and we agree that good faith participation in this informal process is required and must be completed as set forth above before either party can initiate arbitration regarding any Dispute. 

3. Binding Arbitration. If we cannot reach an agreed upon resolution with you regarding a Dispute within a period of thirty (30) days from the time informal dispute resolution commences under the Initial Dispute Resolution provision above, then either you or we may initiate binding arbitration, which will be the sole means to resolve any Dispute, subject to the terms set forth below and except for claims brought in small claims court or unless you opt out. Specifically, all Disputes shall be finally resolved exclusively through binding arbitration administered by the American Arbitration Association (“AAA”) in San Francisco, CA, and through a single mutually agreed upon arbitrator, in accordance with the provisions of the AAA’s Consumer Arbitration Rules, available at www.adr.org or by calling the AAA at 1.800.778.7879. YOU AND X HEREBY EXPRESSLY WAIVE THE RIGHT TO A TRIAL BY JURY OR JUDGE.

The arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any Dispute, including, but not limited to, any claim that all or any part of these X Developer Agreement are void or voidable, or whether a Dispute is subject to arbitration. The arbitrator shall be empowered to grant whatever relief would be available in a court under law or in equity, provided that such relief (including injunctive relief) is limited to your individual circumstances. Notwithstanding the requirements of this arbitration provision, if the Dispute involves a claim for public injunctive relief, you may choose to sever that claim from the arbitration proceeding and bring it in any court of proper jurisdiction. The arbitrator’s award shall be written and binding on the parties and may be entered as a judgment in any court of competent jurisdiction.

YOU HAVE ONE YEAR TO BRING A CLAIM AGAINST X, UNLESS YOU OPT OUT. You must bring any claim against X within one (1) year after the date on which the claim arose, unless applicable law provides that the normal statute of limitations for that claim may not be shortened by agreement. If you do not bring a claim within this period, you waive, to the fullest extent permitted by law, all rights you have to such claim and X will have no liability with respect to such claim.

1. Filing Process and Costs. To start an arbitration, you can get submission instructions at: https://adr.org/Support. X will pay your initial filing fee of $200 and costs of the arbitration up to the extent required and as defined in the AAA Consumer Arbitration Rules, but in no greater amounts than those set forth in this provision. If, however, the arbitrator determines that claims were filed for the purposes of harassment or were patently frivolous, the arbitrator can reallocate the arbitrator’s compensation and administrative fees, including the filing and hearing fees, as set forth in the AAA Consumer Arbitration Rules. The arbitration rules also permit you to recover attorneys’ fees in certain cases. The parties understand that, absent this mandatory provision, they would have the right to sue in court and have a jury trial. They further understand that, in some instances, the costs of arbitration could exceed the costs of litigation and the right to discovery may be more limited in arbitration than in court.

2. Location. Arbitration will take place on a documents-only basis or you can choose to conduct the proceedings by telephone, video, or in-person. For in-person arbitration, the proceedings will be in the city or county where you reside or, if you do not reside in the United States, in the State of California, County of San Francisco.


4. 30-Day Right to Opt Out.  If you wish to opt out and not be bound by these arbitration provisions set forth above, you can send written notice of your decision to opt out to the following address:

X Corp.
Attn: Legal Department - Arbitration Opt Out
1355 Market Street, Suite 900
San Francisco, CA 94103

If you’ve already purchased a Paid Service, you may also submit your opt out notice via the support link available in the navigation menu of the Developer Site under the payment or subscription settings. 

Your written notification must include your name, X account handle, the email address or phone number associated with your account handle, and a clear statement that you do not wish to resolve Disputes with X.

The notice must be sent within 30 days of your first payment for a Paid Service, otherwise you shall be bound to arbitrate disputes in accordance with the terms of those provisions. Your decision to opt out of this arbitration provision will have no adverse effect on your relationship with X or the delivery of features or services to you by X. If you opt out of those provisions, X also will not be bound by them.

5. Changes to this Section. This Dispute Resolution section survives the end of the relationship between you and X, including cancellation of or unsubscribing from any services or communications provided by X.

6. Injunctive Relief. Notwithstanding the foregoing, you agree that money damages would be an inadequate remedy for X in the event of a breach or threatened breach of this Agreement protecting X's intellectual property or Confidential Information, and that in the event of such a breach or threat, X, in addition to any other remedies to which it is entitled, is entitled to such preliminary or injunctive relief (including an order prohibiting Company from taking actions in breach of such provisions), without the need for posting bond, and specific performance as may be appropriate. The parties agree that neither the United Nations Convention on Contracts for the International Sale of Goods, nor the Uniform Computer Information Transaction Act shall apply to this Agreement, regardless of the states in which the parties do business or are incorporated. No waiver by X of any covenant or right under this Agreement will be effective unless memorialized in a writing authorized by X.

Developer Policy


X + Developers 

X loves developers. We’re delighted and amazed by the tools and services this community creates by harnessing the power of X data. As part of our commitment to this community, we aim to provide data access that is open and fair for developers, safe for people on X, and beneficial for the X platform as a whole. To further these goals we’ve crafted the Developer Policy as a guide to help people understand our rules and expectations about appropriate API and X Content usage.

This Developer Policy (“Policy”) provides rules and guidelines for developers who interact with X’s ecosystem of applications, services, website, web pages and content. It is part of your contract with X governing access to and use of the X API and X Content (either as part of the Developer Agreement or other written agreement with X). Policy violations are considered violations of your agreement. This Policy may be changed from time to time without notice. Capitalized terms used in this Policy, which are not defined in this Policy, will have the respective meanings ascribed to them in the Developer Agreement or the Master License Agreement.


Using this policy

We’ve structured this policy to make it as easy to follow as possible. Please keep information from the following policy sections top of mind as you use the X API and X Content:

1. Set Yourself Up for Success - You are responsible for complying with all X policies. It’s important that you review and understand this Policy, as well as the policies we link to in this document, before you access the X API and X Content. The time spent reviewing our policies may save you hours of rework down the road.

2. Privacy and Control are Essential - Protecting and defending the privacy of people on X is built into the core DNA of our company. As such, we prohibit the use of X data in any way that would be inconsistent with people’s reasonable expectations of privacy. By building on the X API or accessing X Content, you have a special role to play in safeguarding this commitment, most importantly by respecting people’s privacy and providing them with transparency and control over how their data is used.

3. Follow the Platform Usage Guidelines - Getting approved to access the X API and X Content is just the first step. Our Platform Usage Guidelines should be your first stop anytime you have questions about how to ensure policy compliance for your planned use of the X platform.

We’ve provided a lot more detail on what each of these three key sections mean below. Please review them carefully to ensure that your usage of the X API and X Content is consistent with our policies. 

If we believe you are in violation of this Policy (or any other X policy), we may suspend or permanently revoke your access to the X API and X Content. 

Finally, please note that X may monitor your use of the X API to improve the X Applications, to examine any commercial use, and to ensure your compliance with your approved use case and this Policy.

Thanks for reading, and thank you for building with us! We look forward to seeing what you create!


Set yourself up for success

You can avoid many potential pitfalls while using the X API by ensuring that your service has been built the right way from day 1. This section of the Developer Policy contains rules that all developers must follow before using the X API or X Content.

We review all proposed uses of the X developer platform to verify policy compliance — so you’re required to disclose (and update, as applicable) your planned use of the X API and X Content in order to be granted and to maintain access. All new developers must apply for a developer account to access the X API. Current developers without an approved developer account must apply for one as directed to do so by X. As part of this process, you’ll need to provide us with a written description of your intended uses of the X API and X Content.

Your use case description is binding on you, and any substantive deviation from it may constitute a violation of our rules and result in enforcement action. You must notify us of any substantive modification to your use case and receive approval before you may begin using X Content for that new purpose. Failure to do so may result in suspension and termination of your API and data access. 

By building on the X API or accessing X Content, you must comply with ALL X policies. These include this Developer Policy, the Automation Rules, the Display Requirements, the API Restricted Uses Rules, the X Rules, and the X Brand Resources, as well as any other agreements you enter into with X relating to your use of the X API or X Content, including but not limited to the Developer Agreement or a Master Licensing Agreement or Order (as applicable). You must also comply with any modifications to these policies and any new policies launched by X. It is your responsibility to monitor the use of your service and to design your service to prevent violations of X policy by people who use it. Failure to do so may result in suspension or termination of your API and X Content access.

You may not register multiple applications for a single use case or substantially similar or overlapping use cases. In this context, a “use case” is a consistent set of analyses, displays, or actions performed via an application. Please note that providing the same service or application to different people (including “white label” versions of a tool or service) counts as a single use case.

As a single exception to these rules, you may create and use a maximum of 3 applications for development, staging, and production instances of the same service. These apps must be registered to a single account, and should be clearly identified (in the name and description) as dev, staging, and prod instances of a single service. You may not use development or staging applications for production purposes.

You must keep all API keys or other access credentials private. You may not use, and may not encourage or facilitate others to use, API keys or other access credentials owned by others.

Your license agreement with X limits your use of the X API and X Content. Among other things, the X API has rate limits which help to ensure fair data usage and to combat spam on the platform. You may not exceed or circumvent rate limits, or any other limitations or restrictions described in this Policy or your agreement with X, listed on the Developer Site, or communicated to you by X.

You may not remove or alter any proprietary notices or marks on X Content received via the X API. This helps to make sure that people know where X Content is coming from, and who it belongs to.

For data integrity and platform health reasons, you may not interfere with, intercept, disrupt, or disable any features of the X API or the X service. In other words, use the APIs as intended and documented on developer.x.com. Refer to our HackerOne guidelines for more details about acceptable use.


Privacy and control are essential

X takes privacy seriously, and we expect everyone using X Content and the X API to do the same. Any use of the X developer platform, X API, or X Content in a manner that is inconsistent with peoples’ reasonable expectations of privacy may be subject to enforcement action, which can include suspension and termination of API and X Content access.

Your commitment to privacy and control must extend to all uses of X Content and all aspects of the service that you build using our API. To that end, the people using your service must understand and consent to how you use their data, and how you access X on their behalf. This can be accomplished through providing people with a clear, comprehensive, and transparent privacy policy, as well as ensuring that you get express and informed consent from each person using your service before taking any action on their behalf. Please note that a person authenticating into your service does not by itself constitute consent.


Consent & permissions

In particular, you must get express and informed consent from people before doing any of the following:

  • Taking any actions on their behalf. This includes (but is not limited to): 
    • Posting content to X
    • Following/unfollowing accounts
    • Modifying profile or account information
    • Adding hashtags or any other content to Posts
  • Republishing content accessed by means other than via the X API or other X tools
  • Using someone’s X Content to promote a product or service
  • Storing non-public content such as Direct Messages (DMs), or any other private or confidential information

  • Sharing or publishing protected content, or any other private or confidential information

If your service allows people to post content to X you must do the following before publishing:

  • Show exactly what will be published

  • Make it clear to people using your service what geo information (if any) will be added to the content

If your service allows people to post content to both your service and X, you must do the following before publishing:

  • Obtain permission to post the content

  • Explain where you will post the content

You must respect the protected and blocked status of all X Content. You may not serve content obtained using one person’s authentication token to a different person who is not authorized to view that content.

  • Protected accounts: A protected account’s content is only available to people who have been approved by the owner to follow that account. So, if you run a service that accesses protected accounts, you may only do so to serve such content to the specific people with permission to view that content.

  • Blocked accounts: People on X are able to block access to their accounts for any reason they choose. Commingling information obtained from tokens (or any other API-based action) to bypass this choice is not permitted.

As Direct Messages (DMs) are non-public in nature, services that provide DM features must take extra steps to safeguard personal privacy. You may not serve DM content to people who are not authorized to view that content. If your service provides DM functionality you must also:

  • Notify people if you send read receipt events for DMs. You can do this by providing a notice directly in your service, or by displaying read receipts from other participants in a conversation.
  • Get consent before configuring media to be sent in a DM as "shared" (i.e. reusable across multiple DMs). If you do allow media in a DM to be “shared,” you must provide a clear notice that this content will be accessible to anyone with the media’s URL.


Content compliance

If you store X Content offline, you must keep it up to date with the current state of that content on X. Specifically, you must delete or modify any content you have if it is deleted or modified on X. This must be done as soon as reasonably possible, or within 24 hours after receiving a request to do so by X or the applicable X account owner, or as otherwise required by your agreement with X or applicable law. This must be done unless otherwise prohibited by law, and only then with the express written permission of X.

Modified content can take various forms. This includes (but is not limited to): 

  • Content that has been made private or gained protected status
  • Content that has been suspended from the platform

  • Content that has had geotags removed from it

  • Content that has been withheld or removed from X


Off-X matching

We limit the circumstances under which you may match a person on X to information obtained or stored off-X. Off-X matching involves associating X Content, including a X @handle or user ID, with a person, household, device, browser, or other off-X identifier. You may only do this if you have express opt-in consent from the person before making the association, or as described below.

In situations in which you don’t have a person’s express, opt-in consent to link their Xidentity to an off-X identifier, we require that any connection you draw be based only on information that someone would reasonably expect to be used for that purpose. In addition, absent a person’s express opt-in consent you may only attempt to match your records about someone to a X identity based on:

  • Information provided directly to you by the person. Note that records about individuals with whom you have no prior relationship, including data about individuals obtained from third parties, do not meet this standard; and/or

  • Public data. “Public data” in this context refers to:

    • Information about a person that you obtained from a public, generally-available resource (such as a directory of members of a professional association)

    • Information on X about a person that is publicly available, including:

      • Posts

      • Profile information, including an account bio and publicly-stated location

      • Display name and @handle


Your privacy policy

You must display your service’s privacy policy to people before they are permitted to download, install, or sign up to your service. It must disclose at least the following information:

  • The information that you collect from people who use your service

  • How you use and share that information (including with X)

  • How people can contact you with inquiries and requests regarding their information

Your privacy policy must be consistent with all applicable laws, and be no less protective of people than X’s Privacy Policy and the privacy policy of our other services and corporate affiliates. You must cease your access to the X API and the use of all X Content if you are unable to comply with your and/or X’s Privacy Policy.


Using geo-data

Use of geo data comes with additional restrictions due to the sensitive nature of this information. If your service adds location information to Posts, you must disclose to people:

  • When you add location information

  • Whether you add location information as a geotag or annotations data

  • Whether your location information is listed as a place, or as geographic coordinates

If your application allows people to post with their location you must comply with X’s geo guidelines in full. 

Any use of location data or geographic information on a standalone basis is prohibited. You may not (and may not permit others to) store, aggregate, or cache location data and other geographic information contained in X Content, except as part of a Post. For example, you may not separate location data or geographic information out from Posts to show where individuals have been over time. Heat maps and related tools that show aggregated geo activity (e.g., the number of people in a city using a hashtag) are permitted.


X passwords

You may not store X passwords, or request that people provide their X password, account credentials, or developer application information (including consumer key) to you directly. We suggest the use of Sign-in with X as the authentication tool to link your service and people on X.


Platform usage guidelines

Have you taken care to review X’s policies and set up your API access the right way? Does your service follow X’s privacy and control guidelines? If you can answer yes to these two questions, then you are ready to start using the X API and X Content. X’s Platform Usage Guidelines provide the assistance needed to ensure that your use of X Content is compliant from day 1 throughout the lifecycle of your service. We suggest reviewing these rules on a regular basis to make sure that your integration is operating in a way that is safe and beneficial to people on X and the X platform as a whole.


Spam, bots, and automation

The use of the X API and developer products to create spam, or engage in any form of platform manipulation, is prohibited. You should review the X Rules on platform manipulation and spam, and ensure that your service does not, and does not enable people to, violate our policies.

Services that perform write actions, including posting Posts, following accounts, or sending Direct Messages, must follow the Automation Rules. In particular, you should: 

If you’re operating an API-based bot account you must clearly indicate what the account is and who is responsible for it. You should never mislead or confuse people about whether your account is or is not a bot. A good way to do this is by including a statement that the account is a bot in the profile bio.


X performance benchmarking

You may not use the X API to measure the availability, performance, functionality, or usage of X for benchmarking, competitive, or commercial purposes. For example, you should never use the X API to:

  • Calculate aggregate X metrics, such as the total number of Monthly Actives (MAs) or Daily Actives (DAs)

  • Calculate aggregate X Post metrics, such as the total number of Posts posted per day, or the number of account engagements

  • Measure or analyze the responsiveness of X

  • Measure or analyze spam or security on X, except as permitted below

We support research that helps improve conversational health on X. You may not publicly disclose any research or findings concerning, or develop, create, or offer services using, the X API or X Content that measure, analyze, or attempt to identify behaviors or content which violate X policies without express written permission from X.

DSA Researchers: If you need to contact X relating to access under Art. 40 of the Digital Services Act, please contact EU-Questions@X.com. If you wish to apply for researcher access, please submit an application.


Public display of Posts

You must maintain the integrity of all X Content that you display publicly or to people who use your service. If you don’t use X for Websites to display content, then you must use the X API to retrieve the most current version available for display. If displayed content ceases to be available through the X API, then you must remove it from your service as soon as reasonably possible, or within 24 hours after the receipt of a removal request from X, or the applicable X account owner, or as otherwise required by applicable law.

There are specific rules you must follow if you display X Content offline. Follow the guidelines for using Posts in broadcast if you display Posts offline. 

If you embed or display Posts, you must contact us about your X API access if your site exceeds 10 million daily impressions. X reserves the right to require additional terms as a condition to your use of the X API. Additional restrictions on X for Websites developer use include:

  • Embedded Posts and/or embedded timelines

    • You must provide people with legally sufficient notice that fully discloses X’s collection and use of data about browsing activities on your website, including for interest-based advertising and personalization. You must also obtain legally sufficient consent from people for such collection and use
    • You must provide legally sufficient instructions on how people can opt out of X’s interest-based advertising and personalization as described here
  • X for Websites widgets

    • You must ensure that people are provided with clear and comprehensive information about, and consent to, the storing and accessing of cookies or other information on their devices as described in X’s cookie use, where providing such information and obtaining such consent is required by law
  • Services targeted to children under 13

    • Services targeted to children under 13 must opt out of tailoring X in any embedded Post and/or embedded timelines by setting the opt-out parameter to be ‘true’ as described here

Content redistribution

The best place to get X Content is directly from X. Consequently, we restrict the redistribution of X Content to third parties. If you provide X Content to third parties, including downloadable datasets or via an API, you may only distribute Post IDs, Direct Message IDs, and/or User IDs (except as described below). 

In total, you may not distribute more than 1,500,000 Post IDs to any entity (inclusive of multiple individuals associated with a single entity) within any 30 day period unless you have received written permission from X. In addition, developers may provide up to 500 public Posts Objects and/or User Objects to each person who uses your service on a daily basis if this is done via non-automated means (e.g., download of spreadsheets or PDFs).

Academic researchers are permitted to distribute Post IDs and/or User IDs solely for the purposes of non-commercial research on behalf of an academic institution, and that has been approved by X in writing, or peer review or validation of such research. Only as many Post IDs or User IDs that is necessary for such research, and has been approved by X may be used. 

Any X Content provided to third parties remains subject to this Policy, and those third parties must agree to the X Terms of Service, Privacy Policy, Developer Agreement, and Developer Policy before receiving such downloads. You may not enable any entity to circumvent any other limitations or restrictions on the distribution of X Content as contained in this Policy, the Developer Agreement, or any other agreement with X.

Note: This Section does not apply to researchers with X API access via Art. 40 of the EU Digital Services Act (2022) (“DSA”), who are instead subject to the procedures and restrictions set forth in the DSA and the Developer Agreement.


Pay to engage

Your service shouldn’t compensate people to take actions on X, as that results in inauthentic engagement that degrades the health of the platform. As you use the X API you may not sell or receive monetary or virtual compensation for any X actions. This includes, but is not limited to, Posts, follows, unfollows, reposts, likes, comments, and replies.


Service authenticity

You must clearly identify your service so that people can understand its source and purpose. Don’t use names, logos, or URLs that mask your service’s identity and features, or that falsely imply an affiliation with X or third parties. Note that creating applications for the purpose of selling names, or to prevent others from using names, is prohibited.

You may not use any URL (including shortened URLs) for your service that directs people to:

  • A site that is unrelated to your service

  • A spam or malware site

  • A site that encourages people to violate X policy


X name, logo, and likeness

You may only use and display the X name and logo to identify X as the source of X Content. You should never use the X name and logo, the X Official Partner Program badge, or any other similar marks or names in a manner that creates a false sense of endorsement, sponsorship, or association with X. The X Brand Resources contain detailed information to help you use the X brand in the right way.

You may only use the X Verified Account badge and any other enhanced account categorization as it is reported to you by X through the API. This helps people know that the content your service displays is equivalent to that shown on X.


Advertising on X

There are restrictions regarding how and where you are allowed to advertise around X Content. To start, your advertisements can’t resemble or reasonably be confused by people as a Post. Other rules on advertising include:

  • There must be a clear separation between X Content and your advertisements. You may not place any advertisements within the X timeline other than X Ads.

  • X reserves the right to serve advertising via the X API. If you decide to serve X Ads once we start delivering them via the API, we will share a portion of advertising revenue with you in accordance with the relevant terms and conditions.

  • You may not use X Content, or information obtained from the X API to target people with advertising outside of the X platform.

The following additional rules apply for any use of the X services or features listed below:

X Login

You must present people with easy to find options to log into and out of X, for example via the OAuth protocol. The Sign in with X option must be displayed at least as prominently as any other sign-up or sign-in feature on your service. You must also provide people without a X account the opportunity to create one via X.

Once someone on your service authenticates via Sign in with X you must clearly display their X identity. X identity includes the person’s current X @handle, avatar, and X logo. Any display of someone’s X followers on your service must clearly show that the relationship is associated with X.

X Cards

To ensure a quality experience you must develop your Card to render across all platforms where Cards are displayed. Additional rules that you must follow when using Cards include:

  • You must mark your Post as ‘true’ for sensitive media if you plan to display such media within a Card

  • You must use HTTPS for hosting all assets within your Card. Your Card should never generate active mixed content browser warnings

  • Audio and video content should include stop or pause controls, and default to ‘sound off’ for videos that automatically play content

You may not exceed or circumvent X’s limitations placed on any Cards, including the Card’s intended use. Additional restrictions on Cards use include:

  • You may not place third-party sponsored content within Cards without X’s approval

  • You may not attach monetary incentives (including virtual currency) within your Card or on X from your Card

  • You may not include content or actions within your Card that are misleading or not contextually relevant, such as URLs and media.

  • You may only attach an App Card to a Post when someone is explicitly promoting or referring to the app in the Post
