  • Read-only protocol probe: Protocol response unconfirmed

    22 Oct 2026, 02:55 UTC · Endpoint did not return a JSON protocol response LocalMark sent no message and did not request task creation.

  • Unsigned card

    This card does not provide a digital signature. Checked 22 Oct 2026, 02:55 UTC.

  • 30-day card check history

    1 of 1 recorded card checks passed in the last 30 days. These are periodic observations, not continuous uptime monitoring.

  • Publisher claim

    No publisher claim has been completed for this listing.

Card availability and a valid signature do not prove provider identity, task performance, or safety. Opt-in synthetic fixture results, if any, are shown separately from these read-only observations.

Publisher-authorized synthetic tests

Publisher: set up test evidence →

No current fixture result · Not yet checked

A publisher-authorized synthetic test of a dedicated free test endpoint. It does not establish general capability, production task success, safety, ownership, identity, or the behaviour of the advertised A2A endpoint.
