PolicyCheck

PolicyCheck A2A Agent

JSON-RPC 2.0 Agent-to-Agent endpoint at https://policycheck.tools/api/a2a, discovered through an A2A agent card served at the legacy /.well-known/agent.json path (protocolVersion 0.2.0, seven skills: comprehensive policy analysis, quick risk check, return / shipping / warranty / terms analysis and signed seller assessment). The endpoint is stateless — message/send only, tasks/get returns -32001 — answered an anonymous request live on 2026-09-19, and returns a completed task carrying the same structured fields as POST /api/check. The card grades conformant on the A2A 1.0.0 hard checks; its documentationUrl and pricing URLs are dead.
