# /core/v1/* is deprecated

api.wikimedia.org deprecated /core/v1/* without giving a shutdown date yet.

The provider deprecated the /core/v1/* endpoints without a specific shutdown date, noting that a gradual deprecation is scheduled to begin in July 2026. This change impacts all requests targeting /core/v1/*. Once removed, these calls fail.

## What to use instead

Call the equivalent MediaWiki REST API endpoints directly on the wiki itself at {wiki}/w/rest.php/v1/... as listed in the endpoint map. Replacement routes are not announced yet, so moving now requires switching to the per-wiki REST API.

The replacement routes are not announced yet: moving now means the per-wiki REST API.
