  description: The newer MediaWiki Core REST API, exposed per wiki at /w/rest.php. It offers a smaller, streamlined surface than the Action API for fetching page content, history, search, files, and revisions. On Wiktionary it serves the same content as the Action API in a more developer-friendly JSON shape. All content is CC BY-SA 4.0.
