  title: Wikivoyage MediaWiki Action Authentication Meta API
  description: 'The MediaWiki Action API is the primary programmatic interface for Wikivoyage, exposed at https://en.wikivoyage.org/w/api.php. All operations dispatch via the ?action= query parameter. The API supports JSON, XML, and PHP serialization; JSON is the recommended format.


    Wikivoyage covers travel destinations worldwide and the Action API enables retrieval of travel destination articles, accommodation listings, sightseeing information, and practical travel advice. Supports both anonymous reads and authenticated writes via OAuth 2.0.


    Wikimedia Foundation API guidelines require a contactable User-Agent header, serial (not parallel) calls for bulk work, and the maxlag parameter for automated clients.'
