Wikimedia REST API
The Wikimedia REST API offers access to Wikimedia's content and metadata in machine-readable formats. Focused on high-volume use cases, it tightly integrates with Wikimedia's globally distributed caching infrastructure. As a result, API users benefit from reduced latencies and support for high request volumes.
The REST API along with its documentation is available for all major Wikimedia projects at the location /api/rest_v1/. For example, for the English Wikipedia it is available at https://en.wikipedia.org/api/rest_v1/.
While the functionality offered by most projects closely matches that on English Wikipedia, there are some noteworthy exceptions:
- wikimedia.org offers cross-project information like page view metrics.
- en.wiktionary.org offers an experimental definition end point, exposing Wiktionary information as structured data. Support for other languages is under discussion.
The REST API follows this API versioning policy.
Terms and conditions
- To avoid impacting other API users, limit your clients to no more than 200 requests/sec to this API overall. Many entry points additionally specify and enforce more restrictive rate limits.
- We ask you to set a unique
Api-User-Agentheader that allows us to contact you quickly. Email addresses or URLs of contact pages work well.
For the REST API included with MediaWiki 1.35 and later, see the MediaWiki Core REST API.
