Batch Identifier Pipeline (up to 50 checks, 1 payment)

Machine-to-Machine Conformance API · batch-validate

$0.05 / call 3 free calls/day No signup

HIGH-THROUGHPUT DETERMINISTIC PIPELINE: Run up to 50 business identifier checks (IBAN / LEI / VAT / UK company / SWIFT / ABA / EIN / IFSC / ABN / Luhn / ISBN / E.164 / SEDOL / ISIN / EAN-13 / GSTIN / context-distill) in ONE paid call: one voucher, one settlement, one signed XDR-1 receipt covering the whole batch. 10x cheaper per item; essential for autonomous batch invoice processing.

Honest Scope Guarantee

One paid call covers every check in the batch and ONE signed receipt covers the whole batch. Each item's scope field states its exact assurance level.

Quickstart & Execution

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

curl -X POST https://api.code402.dev/v1/tools/batch-validate/call \
  -H "content-type: application/json" \
  -d '{"items":[{"tool":"iban-check","value":"GB82 WEST 1234 5698 7654 32"},{"tool":"lei-check","value":"529900T8BM49AURSDO55"},{"tool":"vat-mod97-check","value":"BE0417497106"}]}'

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.
