Belgian VAT MOD-97 Check

Machine Tool Interface · vat-mod97-check

$0.005 / call5 free sandbox calls/day No signup

Check the supported Belgian VAT format and MOD-97 checksum. BE only; not VIES, other EU VAT formats, registration status or tax compliance.

Honest Scope Guarantee

Checksum-verifiable: a real check-digit algorithm runs offline, so a malformed or transposed identifier is rejected deterministically. It does NOT prove the account/record exists or that its holder is honest — pair with your existing fraud process. BE mod-97 family; not a VIES registration lookup.

Quickstart & Execution

cURL (5 configured free sandbox calls/day; real production identifiers require x402 or ck_live_)

curl -X POST https://api.code402.dev/v1/tools/vat-mod97-check/call \
  -H "content-type: application/json" \
  -d '{"vat_number":"BE0417497106"}'

The configured free sandbox allowance is 5 calls/day on synthetic test vectors; real production counterparty identifiers immediately require payment or a prepaid ck_live_ key. 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.
