These are server-to-server endpoints: they are not CORS-open, so a key must never be used from a browser. Keys are scoped; a request for a scope the key lacks returns 403. Any id outside the key's workspace returns 404, never 403. All list endpoints are keyset-paginated and return accepted responses only (withheld/quarantined submissions are excluded)."
