Reference for the Discogs database endpoints (api.discogs.com) — the read-only catalog of music metadata. Make sure to use this skill whenever the task involves fetching or searching Discogs Releases, Masters, Artists, or Labels, even if "database" isn't said: getting a release/master/artist/label by id, listing an artist's or label's releases, master versions, release stats and community/user ratings (including PUT/DELETE a user's rating), pulling release videos, or running /database/search by query, barcode, catalog number, type, genre, year, etc. Also use it when deciding which query-string filters or sort options a database call supports.
