Valid AgentCard
10/10
Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).
partial
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. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.

fail
Protocol version
0/10
No protocolVersion in card.
How to earn +10 points
Declare protocolVersion
Add `"protocolVersion": "1.0"` (Major.Minor, no patch number — §3.6) to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

Uptime track record
0/15
0/16 probes succeeded (0% uptime).
How to earn +15 points
Stabilise uptime
We probe every agent on a tiered schedule and grade the last 30 days. Sustained 99 %+ uptime over 20+ conclusive probes scores full points. Probes you refuse us (HTTP 429/403, a WAF challenge, robots.txt) no longer count against you either way, so what is left is genuine unavailability — usually a transient 5xx on cold start.

Skill declaration
6/10
Declares 1 skill, usable but thin.
How to earn +4 points
Declare your skills
Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags` — `description` and `tags` are REQUIRED on AgentSkill since A2A v1.0, and tags are what discovery filters match on. We canonicalise these into the global skill taxonomy on next probe.

Verified Identity
5/10

How to earn +5 points
Verify your domain ownership
