Check your Agent Card.

Get specific fixes before submitting a public A2A card. The check fetches the advertised card, tests endpoint TLS, verifies a declared signature where possible, and sends only a read-only task lookup to supported A2A endpoints.

Card structure passes LocalMark's intake check.

Checked 29 Oct 2026, 08:38 UTC. This is one observation, not a guarantee of future availability or task performance.
