As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • check_media

    Check a file against a platform without storing it. With convert, also says whether conversion can fix it.

  • delete_media

    Delete an uploaded file now (call after the post is published).

  • get_media

    Status (converting, ready, failed), URL, expiry and fetch count of an uploaded file.

  • upload_media

    Upload an image or video for a social platform. Returns a public URL that passes the platform media rules, or the problems with fixes. With convert, a fixable file comes back as status "converting": poll get_media until status is "ready" (url set) or "failed". Give the URL to the platform API (image_url / video_url), then call delete_media.
