Call via Rooms

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

$0.012 per call, all in (finance-api.kdlcfa.workers.dev's listed price $0.01 plus the Rooms margin; the 402 quotes the live price)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/finance-apikdlcfaworkersdev -H 'Content-Type: application/json' -d '{"path":"/us30y-yield","query":{}}'

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /us30y-yield), query and body go to finance-api.kdlcfa.workers.dev 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.
