The MediaWiki API gives you programmatic access to content on any Wikimedia wiki. You can use the API to search and display wiki pages, get media files, edit pages, and manage wikis.

The API Portal was originally created by the Wikimedia Foundation Platform Engineering Team in 2020 as part of the Platform Evolution program. It had these objectives: Provide documentation for API endpoints served through the API Gateway and allow for creating and managing Wikimedia OAuth 2.0 clients through a single site.

To create an API key, select Create key, and complete the registration form. App credentials let you build an app to publish and share. Wikimedia API requests are rate limited based on client ID, so you should create one set of credentials per app. To create credentials, select an app type, and provide a redirect URL.
