            Dated version of the API contract to pin this request to. Omit it
            and the request is served under `2026-08` — the oldest supported
            version, so an existing integration is never moved by a release. A
            malformed or unsupported value is rejected with `400
            invalid_api_version` rather than falling back silently. The version
            actually served is echoed as `X-Mesh-Version` on every response,
            including errors.
