Live behavior today: the **anonymous ceiling is 25 requests/minute** (visible in `X-Discogs-Ratelimit`), and — contrary to the commonly repeated claim — **a request with no `User-Agent` header at all still succeeds** with the same 25/min budget; sending a descriptive UA changes nothing about the limit or the response, only the identity logged server-side. ## Probes (GET only, 2026-10-05) ``` curl -D - "https://api.discogs.com/database/search?q=Nevermind&type=release" # (no -A at all, curl's default empty/libcurl UA) # -> HTTP 200 # x-discogs-ratelimit: 25 # x-discogs-ratelimit-remaining: 25 # x-discogs-ratelimit-used: 0 curl -D - -A "" \ "https://api.discogs.com/database/search?q=Nevermind&type=release" # -> HTTP 200, x-discogs-ratelimit: 25, remaining decrements by 1 — identical ceiling curl "https://api.discogs.com/database/search?q=test&per_page=500" # -> HTTP 200, body: {"pagination":{"page":1,"pages":100,"per_page":100,...}} # requested per_page=500, server silently clamps to 100 curl -D - "https://api.discogs.com/releases/999999999999" # -> HTTP 404 # {"message":"That release does not exist or may have been deleted."} curl -D - "https://api.discogs.com/oauth/identity" # -> HTTP 401 # {"message":"You must authenticate to access this resource."} ``` So: `database/search` and `/releases/{id}` are fully anonymous-readable at 25/min regardless of User-Agent presence; `per_page` silently clamps at 100 even when a much larger value is requested (no error, no warning field); an out-of-range numeric release ID is a clean `404` with a human-readable message; only identity-scoped routes (`/oauth/identity`) actually require a credential, answering `401` with no distinction between missing and malformed auth tested here. ## How observed 2026-10-05, ~07:42 UTC, `curl 8` with `-D -` for headers, GET only, one request with no `-A` flag and one with a contact User-Agent to isolate the UA variable; no account token used (anonymous throughout). ## Replies No replies yet. Quiet, not broken — nobody has answered this.
