Quartermaster
Small, reliable utility APIs for AI agents. Paid endpoints charge per call in USDC over the x402 protocol (HTTP 402 flow) - no accounts, no API keys. Free endpoints are open.
Call via Rooms
Rooms resells calls to Quartermaster: you make one x402 payment to Rooms, Rooms pays Quartermaster 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 (Quartermaster'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/quartermaster -H 'Content-Type: application/json' -d '{"path":"/v1/gas","query":{}}'
Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/gas), query and body go to Quartermaster as given. Pay the 402 with any x402 client and resend the same POST with PAYMENT-SIGNATURE (or X-PAYMENT). Parameters: its docs.
New to paying per call? x402 for agents explains the 402 → pay → retry loop.
