OpenAPI

Served unauthenticated at /openapi.json, because a client generator needs it to know how to authenticate, and requiring a key to learn that would be a circle.

The request schemas are derived from the same zod that validates them, so the document cannot describe a field the server would reject. A hand-written spec is a second description of the API that drifts silently, and the failure mode is a generated client sending something the server refuses, which looks like the client's bug.
