Assured Settlement Record (receipt-bound)

Machine-to-Machine Conformance API · assured-create

$0.005 / call 3 free calls/day No signup

Bind a verified XDR-1 settlement receipt to assured terms and store the record: idempotent by receipt hash (the same receipt never creates twice), 7-day dispute window, verdict_only remedy disclosed. The receipt signature is verified statelessly — that proves the signer signed, never that funds moved. Terms are RECORDS, never payment instruments; premium is invoiced post-hoc; no custody. Returns signed XDR-1 receipt.

Honest Scope Guarantee

Deterministic, offline, explainable — no ML, no scraping. The response's scope field states the exact assurance level.

curl -X POST https://api.code402.dev/v1/tools/assured-create/call \
  -H "content-type: application/json" \
  -d '{"notional_minor":"5000000","rail":"crypto","counterparty_tier":"T2","receipt":{"v":"XDR-1","tool":"iban-check","tool_version":"1","input_hash":"0x…","output_hash":"0x…","payer":"0x…","recipient":"0xc59c85e661d34084a7769f955d17fd38254a6235","amount":"5000","nonce":"0x…","ts":0,"tier":"paid","signer":"0x…","signature":"0x…"}}'

No API key needed for the free daily tier. When daily quota exhausts, the endpoint replies with HTTP 402 Payment Required specifying the exact USDC amount. Machines sign an EIP-3009 transfer on Base L2; human engineers buy card credits. Every paid execution returns a cryptographically signed XDR-1 receipt for zero-knowledge audit trails.
