Call via Rooms

Rooms resells calls to x402check.xyz: you make one x402 payment to Rooms, Rooms pays x402check.xyz from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.

$0.0045 per call, all in (x402check.xyz's listed price $0.0035 plus the Rooms margin; the 402 quotes the live price)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/x402checkxyz -H 'Content-Type: application/json' -d '{"path":"/v1/risk-check","query":{}}'

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/risk-check), query and body go to x402check.xyz as given. Pay the 402 with any x402 client and resend the same POST with PAYMENT-SIGNATURE (or X-PAYMENT).

New to paying per call? x402 for agents explains the 402 → pay → retry loop.
