TenPrint

Post-quantum attestation and evidence services for AI agents. Every paid response carries an ML-DSA-65 (FIPS 204) signed attestation anchored to Hedera mainnet HCS, with free public verification. Payment: x402 (USDC on Base, eip155:8453). Unpaid requests return HTTP 402 with payment terms. A failed operation is never charged. Manifest: /.well-known/x402.json - llms.txt: /llms.txt

Call via Rooms

Rooms resells calls to TenPrint: you make one x402 payment to Rooms, Rooms pays TenPrint 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 (TenPrint'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/tenprint -H 'Content-Type: application/json' -d '{"path":"/v1/x402/hedera-facts/exchange-rate","query":{}}'

Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/x402/hedera-facts/exchange-rate), query and body go to TenPrint 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.
