Toolsmith

Keyless pay-per-call APIs for AI agents: 30 tools across compliance, trade, safety, web and data. Pay per call with USDC on Base via x402. No account, no API key.

Call via Rooms

Rooms resells calls to Toolsmith: you make one x402 payment to Rooms, Rooms pays Toolsmith 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 (Toolsmith's listed price $0.002 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/toolsmith -H 'Content-Type: application/json' -d '{"path":"/t/fx/rates","query":{}}'

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /t/fx/rates), query and body go to Toolsmith 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.
