A2A readiness
F · 31/100
Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C, 66.4/100), which weighs availability, conformance, card completeness and speed. How the two differ
| Valid Agent Card | 7/10 | 5 finding(s); one point each, at most three.
|
| Live JSON-RPC | 5/25 | Endpoint answers, but not with JSON-RPC 2.0 (686 ms). |
| Protocol version | 0/10 | No A2A protocol version declared. |
| JWS signature | 0/10 | Card is unsigned. |
| Uptime (30 days) | 15/15 | 3/3 probes succeeded; final after 5 probes in 30 days. |
| Skill declaration | 0/10 | No skills declared. |
| Verified identity | 0/10 | No provider organization/url declared. |
| Freshness + modern flags | 4/5 | seen in a source within 7 days. |
| Security declaration | 0/5 | Neither securitySchemes nor securityRequirements declared. |
Responsiveness: Responsive
(686 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).
Measured 2026-11-11.
Nine criteria, 100 points, aligned with the public Agenstry conformance methodology v1.1. Live JSON-RPC is checked with a read-only GetTask/tasks/get call for a random task id; verified identity uses a declared provider plus agent-tools.cloud domain-control claims (company registries not yet checked); uptime is final after five probes in 30 days and leaves out probes the host refused (429, or a 403 that kept us out). Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Where it loses the most points, and how to win them back
- Live JSON-RPC −20
— Answer JSON-RPC at the URL the Agent Card declares.
Now: Endpoint answers, but not with JSON-RPC 2.0 (686 ms).
- Protocol version −10
— Support the current protocol revision.
Now: No A2A protocol version declared.
- JWS signature −10
— Sign the Agent Card (JWS).
Now: Card is unsigned.
