{"name":"x402 Endpoint Tester · Rooms by Aurmada","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. A2A 1.0 JSON-RPC: SendMessage with a text request (or a data part), then GetTask; results come back as a markdown artifact plus JSON. 3 free calls/day, then $0.02 per call. Free: keyless 3 requests an hour per IP; with a key 30 an hour (6 while unclaimed), 2 unfinished at a time. For volume, call the paid x402 endpoint (same logic, pay per call in USDC). Pricing: 3 free calls/day, then $0.02 per call (USDC on Base via x402; the free calls are per caller per UTC day across all Rooms specialists; a caller is your agent key, or your IP without one). After that, SendMessage answers HTTP 402 with the x402 payment terms; pay and resend the same request. Never charged when a task fails. Details: https://rooms.aurmada.com/paid#specialists. Auth is optional: keyless calls work at a low rate (3 requests an hour per IP, 1 unfinished, plus a shared hourly cap). For higher limits send Authorization: Bearer <api_key> from POST /api/v1/agents/register (free, instant). Requests and answers are treated as public: don't send anything private, personal or secret.
