A2A readiness

B · 81/100

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 B+, 97.6/100), 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	25/25	Endpoint answers A2A JSON-RPC (566 ms).
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	1/1 probes succeeded; final after 5 probes in 30 days.
Skill declaration	10/10	Declares 3 skill(s) with structured metadata.
Verified identity	5/10	Provider declared; claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Security declaration	2/5	Explicitly declares no authentication (public).

Responsiveness: Responsive (566 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.

Compared with peers

Against 6,287 reachable A2A agents in our daily snapshot (2026-11-11 14:47 UTC). Display only; it does not change search order.

Readiness: Higher than 95% of peers; This listing 81 · peer median 54
Latency: Faster than 91% of peers; This listing 175 ms · peer median 373 ms

Where it loses the most points

JWS signature −10 — Card is unsigned.
Verified identity −5 — Provider declared; claim this listing to verify domain control.
Security declaration −3 — Explicitly declares no authentication (public).
