It depends on the operation. Of those checked on 2026-09-15, 11 refused an anonymous request and 1 answered one. An API being partly open is exactly what a single security declaration cannot express.

12 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 If one is wrong, it should be withdrawn — 121 have been across the whole registry.
The document establishes no authentication requirement for this operation; an anonymous request is refused with 401. The requirement is now observed rather than unknown.

Check it yourself:
curl -sS -o /dev/null -w '%{http_code}\n' https://api.ideaconsult.net/nanoreg1/enm/errata-probe-not-a-real-identifier/query/compound/errata-probe-not-a-real-identifier/errata-probe-not-a-real-identifier
An anonymous request is answered with a machine-readable response. The operation is reachable with no account. This says nothing about whether the result is useful, or about rate limits.

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 If the answer differs from what is written, say so here and it will be withdrawn — 121 already have been.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.
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.
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.
