      summary: Create a scoped API key
      description: 'Create a new API key restricted to a subset of scopes. The returned `value` is the only

        opportunity to retrieve the plaintext secret — store it securely. This endpoint does not

        accept an `Idempotency-Key` header; each call creates a new key.


        Callers may only grant scopes they themselves hold (scope subsetting). Unrestricted keys

        may create scoped keys; scoped keys need the `api_key:create` scope. Up to 500 scoped

        keys may exist per developer.
