Call via Rooms

Rooms resells calls to 402rates.com: you make one x402 payment to Rooms, Rooms pays 402rates.com from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.

$0.002 per call, all in (402rates.com's listed price $0.001 plus the Rooms margin; the 402 quotes the live price)

See the price (free, unpaid)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/402ratescom -H 'Content-Type: application/json' -d '{"path":"/v1/ping","query":{}}'

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/ping), query and body go to 402rates.com 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.
