The REST API lets you interact with MediaWiki by sending HTTP requests to unique URLs. You can use the API to build apps and scripts that search wiki pages and explore page history.

Data formats
The API returns data in JSON format.

Methods
The API supports standard HTTP request methods.

URL structure
API endpoints share a consistent URL structure that includes the wiki's base URL, the wiki's install path, and the API version. To learn about API versioning, see the stability policy.

Permissions and authorization
The REST API is designed to use the OAuth extension for user authentication and authorization. However regardless of authentication method, the API responds to the presence of a logged-in user and returns content appropriate to that user's permissions.

Accessing Wikimedia projects using the REST API
You can use the REST API to access Wikipedia, Wiktionary, and other Wikimedia projects in multiple languages. For a complete list of Wikimedia project URLs, see Meta-Wiki’s site matrix.

Request limit
There is no fixed limit on requests to the API, but your client may be blocked if you endanger the stability of a site. To stay within a safe request rate, wait for each request to finish before sending another request.

Client identification
Wikimedia sites require an HTTP User-Agent header for all API requests. This helps identify your app and ensures that system administrators can contact you if a problem arises. Clients making requests without a User-Agent header may be blocked without notice.

The preferred format for a User-Agent header is. Contact information can include a user page on the local wiki, a user page on a related wiki using interwiki linking syntax, a URL for a relevant external website, or an email address. For example, to set a User-Agent header in PHP:

If you are calling the API from browser-based JavaScript, you may not be able to influence the User-Agent header, depending on the browser. To work around this, use the   header. See Meta-Wiki’s User-Agent policy for more information.

Authorization
To authorize your app to act on behalf of a user, follow the OAuth developer guide to register your app and make requests using OAuth.

Licensing and trademarks
Wikimedia content is free to reuse within the terms specified by the applicable license. Licenses can differ between projects, so see the individual project for information about licenses and content reuse. For example, English Wikipedia’s text can be used under the terms of the Creative Commons Attribution Share-Alike license, while media files on Wikimedia Commons are licensed individually as indicated on the file’s information page. For more information about licensing and trademark use, see Meta-Wiki’s developer app guidelines.

Enabling the REST API on your wiki
The REST API is available in MediaWiki 1.34 and later as disabled by default. To enable the REST API on your wiki, add  to.

Extension endpoints
MediaWiki extensions can surface extension-specific API endpoints using the REST API interface. See the REST API extension interface docs to get started. For documentation for REST API endpoints provided by extensions, see the extension docs.

Other APIs
There are two families of REST APIs related to Wikimedia projects: the MediaWiki REST API described on this page and the REST API built on RESTBase. While the MediaWiki REST API is part of the MediaWiki platform and can be enabled on any wiki running MediaWiki 1.34 or later, the RESTBase API serves content specific to Wikimedia projects. If you're looking for the full-featured, RPC-style MediaWiki API, see the Action API.
