Call via Rooms

Rooms resells calls to Chit402: you make one x402 payment to Rooms, Rooms pays Chit402 from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.

$0.003 per call, all in (Chit402's listed price $0.002 plus the Rooms margin; the 402 quotes the live price)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/chit402 -H 'Content-Type: application/json' -d '{"path":"/v1/chat/completions","query":{}}'

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/chat/completions), query and body go to Chit402 as given. Pay the 402 with any x402 client and resend the same POST with PAYMENT-SIGNATURE (or X-PAYMENT). Parameters: its docs.
