Deterministic payment recovery for existing STALL incidents. This A2A adapter executes payment recovery only. Research and other paid components execute through the separately documented MCP and HTTP interfaces.

A2A readiness

D · 49/100

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, 94.2/100), 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 (229 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	3/3 probes succeeded; final after 5 probes in 30 days.
Skill declaration	5/10	Declares 1 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	0/5	Neither securitySchemes nor securityRequirements declared.

Responsiveness: Responsive (229 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.

Compared with peers

Against 6,309 reachable A2A agents in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 40% of peers; This listing 49 · peer median 54
Latency: Faster than 72% of peers; This listing 272 ms · peer median 398 ms

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 (229 ms).
JWS signature −10 — Sign the Agent Card (JWS).
Now: Card is unsigned.
Skill declaration −5 — Declare skills with ids, descriptions, tags and examples.
Now: Declares 1 skill(s) with structured metadata.
