Finds the right one of the 129 pay-per-call SiteCheck Web Intel tools on this host for a task described in plain words, and says how to call it: URL, method, price in USDC and how to pay with x402. Free; it runs no tool itself. The tools are called over HTTP (x402) or MCP at https://api.webintel-api.workers.dev/mcp.

A2A readiness

C · 72/100

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, 93.7/100), 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 (123 ms).
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	5/10	Declares 1 skill(s) with structured metadata.
Verified identity	8/10	Provider declared and domain control verified on agent-tools.cloud (company-registry check not available yet).
Freshness + modern flags	4/5	seen in a source within 7 days.
Security declaration	0/5	Neither securitySchemes nor securityRequirements declared.

Responsiveness: Responsive (123 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
