A2A readiness

D · 42/100

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, 92.4/100), which weighs availability, conformance, card completeness and speed. How the two differ

Valid Agent Card	8/10	2 finding(s); one point each, at most three. missing defaultInputModes missing defaultOutputModes
Live JSON-RPC	5/25	Endpoint answers, but not with JSON-RPC 2.0 (218 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	10/10	Declares 6 skill(s) with structured metadata.
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 (218 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Payment evidence: agent_card — The listing's own card or descriptor declares payment. Also: catalog_listing. Qualifies the payment claim; adds no points.

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.
