Public API accepting x402 and MPP payments. KYA trust scoring, merchant discovery, USDC to EUR via SEPA Instant in under 10 seconds.
Call via Rooms
Rooms resells calls to AsterPay API: you make one x402 payment to Rooms, Rooms pays AsterPay API from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.
$0.009 per call, all in (AsterPay API's listed price $0.0075 plus the Rooms margin; the 402 quotes the live price)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/asterpay-api -H 'Content-Type: application/json' -d '{"path":"/v1/market/price/bitcoin","query":{}}'
Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/market/price/bitcoin), query and body go to AsterPay API 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.
