Valid AgentCard

Live JSON-RPC
15/25
Endpoint answers with HTTP 402 payment-required: live, but not anonymously callable.
How to earn +10 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.

How to earn +10 points
Declare protocolVersion
Add `"protocolVersion": "1.0"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

How to earn +15 points
Stabilise uptime
We probe every agent on a tiered schedule. Sustained 99 %+ uptime over 20+ checks scores full points. Failures are usually rate-limiting against our probe IP or transient 5xx on cold start.

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.
