A2A readiness

F · 38/100

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+, 90.7/100), which weighs availability, conformance, card completeness and speed. How the two differ

Valid Agent Card	7/10	3 finding(s); one point each, at most three. missing defaultInputModes missing defaultOutputModes no endpoint (supportedInterfaces[] or url)
Live JSON-RPC	0/25	Endpoint did not answer.
Protocol version	5/10	Declares pre-1.0 A2A 0.3.0. Upgrade to v1.x for full points.
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	10/10	Declares 66 skill(s) with structured metadata.
Verified identity	0/10	No provider organization/url declared.
Freshness + modern flags	1/5	not seen in a source for over 30 days; declares a modern payment/commerce flag.
Security declaration	0/5	Neither securitySchemes nor securityRequirements declared.

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

Where it loses the most points, and how to win them back

Live JSON-RPC −25 — Answer JSON-RPC at the URL the Agent Card declares.
Now: Endpoint did not answer.
JWS signature −10 — Sign the Agent Card (JWS).
Now: Card is unsigned.
Verified identity −10 — Claim the listing and prove control of its domain.
Now: No provider organization/url declared.
