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.

Direct HTTPS Agent Cards at /.well-known/agent-card.json or /.well-known/agent.json are checked. Five checks per hour per visitor.
