Schema-validated A2A AgentCard returned by the well-known endpoint.

fail Live JSON-RPC 0/25

Card declares a URL but that URL returns 404.

            How to earn +25 points
          

Respond live on JSON-RPC

Implement message/send (or tasks/send on v0.x). Return a 200 with a valid JSON-RPC response. Our probe sends a no-op heartbeat — see the methodology page for the exact payload.

fail Protocol version 0/10

No protocolVersion in card.

            How to earn +10 points
          

Declare protocolVersion

Add `"protocolVersion": "1.0"` to the AgentCard root. Without it, callers can't negotiate v0.x vs v1.0 compatibility.

Docs →

info JWS signature 0/10

Card is unsigned (most published agents are).

info Uptime track record 0/15

Only 3 probes so far — need ≥5 for an uptime grade.

fail Skill declaration 0/10

No skills declared in card. Hard to route to.

            How to earn +10 points
          

Declare your skills

Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags`. We canonicalise these into the global skill taxonomy on next probe.

partial Verified Identity 5/10

Provider declared: AgentUtil (https://agentutil.net). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

            How to earn +5 points
          

Verify your domain ownership

Claim your listing and add the DNS TXT record we generate. Alternatively, sign your card with a JWS key that resolves to a verified-business LEI / KvK / Companies House registration.
