28 Oct 2026, 21:07 UTC · Valid TLS connection to advertised endpoint host; no A2A request sent This does not test the A2A protocol or run a task.
- Read-only protocol probe: JSON-RPC answered; task lookup unavailable
28 Oct 2026, 21:07 UTC · Endpoint answered JSON-RPC, but neither tasks/get (A2A 0.3) nor GetTask (A2A 1.0) is available. Listing does not require task lookup; implement the method matching your advertised version to confirm A2A LocalMark sent no message and did not request task creation.
- Unsigned card
This card does not provide a digital signature. Checked 28 Oct 2026, 21:07 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.
Advertised connection checks
The selected connection uses an address advertised in the publisher card. Read-only observations do not establish task quality or safety.

Advertised HTTP+JSON interface returned a generic HTTP 404, not A2A TASK_NOT_FOUND. Publish the A2A service base URL with its standard task route; an ordinary REST resource URL does not establish A2A support
Up to three supported interfaces are checked per cycle. Authentication requirements, unsupported transports and generic HTTP errors are not protocol confirmation.
