Name it. Get the Spec.

No fake Specs.

Trimmed: the whole answer also carries the Sources, any Alternate Specs and the Validity Issues.

Every answer is one of five

Precision over coverage: when SwaggerBot isn't sure, it says so as plainly as when it is.

Resolved
The name is one API, and its Spec is confirmed to describe it. With Provenance and Sources.
Unconfirmed
The API and a Spec were found, but not confirmed as this API's. The Spec comes with the reasons for doubt.
Ambiguous
The name could mean more than one API. You get the candidates to pick from.
No Spec
The API is known, but no Spec exists at a Provenance you allowed.
Unknown
The name can't be matched to any API.

For agents and programs: the same answers over MCP and the HTTP API, and for people at a terminal, the CLI. From the Index, anyone. Past it, Discovery, with an API key.
