  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.
