pass Valid AgentCard 10/10

Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).

fail Live JSON-RPC 5/25

Endpoint replies but body isn't a valid JSON-RPC 2.0 A2A response.

            How to earn +20 points
          

Respond live on JSON-RPC

Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload.

partial Protocol version 2/10

Declares unrecognised version '5.0'.

            How to earn +8 points

pass Uptime track record 15/15

25/25 probes succeeded (100% uptime).

pass Skill declaration 10/10

Declares 3 skills with structured metadata.

fail Verified Identity 0/10

No provider organisation declared. Anonymous agent.

pass Freshness + modern flags 4/5

seen in upstream source within 0d

partial Security declaration 2/5

Declares 1 security scheme(s) but none use PKCE or mTLS.

            How to earn +3 points
          

Document securitySchemes

Add a `securitySchemes` block to the card describing your auth: `bearer`, `apiKey`, `openIdConnect`, or `mutualTLS`. Routers refuse to call agents that declare no auth model.
