Quickstart & Execution

cURL (Paid-only route — unauthenticated calls return HTTP 402 Payment Required)

curl -X POST https://api.code402.dev/v1/tools/iso4217-currency-check/call \
  -H "content-type: application/json" \
  -d '{"currency":"EUR"}'

This route is paid-only (0 free calls/day); every unauthenticated request returns an HTTP 402 Payment Required challenge with its payment terms. Machines use USDC on Base; card credits (instant Stripe checkout) are enabled in this deployment. Signed XDR-1 receipts authenticate recorded service claims, not independent settlement, delivery or zero-knowledge proofs.
