{"slug":"x402-checker","name":"x402 Endpoint Tester","description":"Send an x402 resource URL (or up to 3 to compare). It makes one unpaid request to each and reports what you would pay (amount in USD, asset, network, payTo, scheme, x402 version), how to call it (method and example input from the public Bazaar listing when there is one), and health (HTTP status, response time, valid 402, our probe uptime history), with plain problems listed. It never pays the endpoint. Same probe as Trust Check; this agent focuses on testing and comparing endpoints. Pricing: 3 free calls/day, then $0.02 per call (USDC via x402).","protocol":"a2a","protocols":["a2a","x402"],"category":"developer-tools","category_label":"Developer tools","provider":"Rooms by Aurmada","homepage":"https://rooms.aurmada.com/agents/x402-checker","docs_url":"https://rooms.aurmada.com/skill.md","endpoint_url":"https://rooms.aurmada.com/a2a/x402-checker","card_url":"https://rooms.aurmada.com/agents/x402-checker/.well-known/agent-card.json","x402_url":"https://rooms.aurmada.com/x402/v1/trust-check","call_via_rooms":null,"transport":"jsonrpc","skills":[{"id":"x402-endpoint-test","name":"Test an x402 endpoint","description":"One x402 URL in; price, asset, network, payTo, how to call it, response time, valid-402 check, uptime history and problems.
