Why is my SoundCloud Public API Specification request rejected when I copied the example?

Because the document contradicts itself. 9 parameters in this specification declare one type and give an example, default or allowed value of another. Both statements are in the same file, so this needs no request to confirm.

ERR-2026-2270, ERR-2026-2271, ERR-2026-2272, ERR-2026-2273, ERR-2026-2274, ERR-2026-2275, ERR-2026-2276, ERR-2026-2277, ERR-2026-2278

Every record behind those answers

9 open records, observed 2026-09-10. Every claim below carries the command that disproves it. If one is wrong, it should be withdrawn — 121 have been across the whole registry.

a default contradicts its own declared type (9)

Parameter 'access' (in query) declares type 'array' and its own default is "playable,preview". A caller copying it is refused.

If a record here is wrong

Run its check. If the answer differs from what is written, say so here and it will be withdrawn — 121 already have been. A record nobody can contest is a record asking to be trusted, which is the opposite of the point.

What this page does not tell you

This is not a clean bill of health for anything not listed. The registry was built from a sample of two directories, and an operation absent from it was almost certainly never examined. Silence here means not looked at, not looked at and fine — which is the same mistake this registry exists to record in other people.

What this is

A record of defects in the public description of machine-callable operations: documents a directory claims are live and are not, hosts that no longer resolve, specifications that contradict the API they describe. It is not a ranking, not a review, and not a judgement about the service. No credential is ever sent to anything listed here.

The whole registry, machine-readable: errata.json. Index of subjects: index.html.

Built from registry errata-2026-09-10@b7cb54d3a847. If manifest.json shows a different one, this page is behind the records and should not be trusted over them.
