Quickstart & Execution

cURL (20 Free Calls/Day • Zero Authentication Required)

curl -X POST https://rail.akrivis.in/v1/tools/japan-supplier-check/call \
  -H "content-type: application/json" \
  -d '{"corporate_number":"7000012050002","iban":"GB82WEST12345698765432"}'

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.
