A2A readiness
D · 47/100
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, 82.8/100), which weighs availability, conformance, card completeness and speed. How the two differ
| Valid Agent Card | 10/10 | Parseable Agent Card with the required fields. |
| Live JSON-RPC | 0/25 | Endpoint did not answer. |
| Protocol version | 10/10 | Declares A2A 1.0 with supportedInterfaces[] (v1 card shape). |
| 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 | 5/10 | Declares 2 skill(s) with structured metadata. |
| Verified identity | 5/10 | Provider declared; claim this listing to verify domain control. |
| Freshness + modern flags | 0/5 | not seen in a source for over 30 days. |
| Security declaration | 2/5 | Declares 1 security scheme(s). |
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.
