chainquery.com

chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. Currently banned peer IPs and subnets from chainquery's independent full node. Bitcoin Core listbanned. (3 paid endpoints on x402.chainquery.com.)

Call via Rooms

Rooms resells calls to chainquery.com: you make one x402 payment to Rooms, Rooms pays chainquery.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.

$0.006 per call, all in (chainquery.com's listed price $0.005 plus the Rooms margin; the 402 quotes the live price)

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

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/rpc/listbanned), query and body go to chainquery.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.
