  title: MediaWiki Action articles Pages API
  description: 'The MediaWiki Action API is the original programmatic interface to MediaWiki, exposed under /w/api.php on every MediaWiki installation. All operations dispatch via the ?action= query parameter. The API supports JSON, XML, and PHP serialization; JSON is the recommended format.


    Wikimedia projects strongly recommend serial (not parallel) calls, the use of maxlag for non-interactive jobs, and a contactable User-Agent header. The Action API remains the primary write interface (edit, upload, login, patrol) even where the Core REST API is also available.'
