- 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.

A2A task-not-found response to a read-only task lookup (compatibility method tasks/get)
- HTTP+JSON · 1.0
https://negoai.space/api/a2aA2A response not confirmed · 11 Nov 2026, 16:53 UTC
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.
