How this service works
Pay-per-call New Zealand utilities via x402 (USDC on Base). Computed from statute (Holidays Act 2003, Te Kāhui o Matariki Public Holiday Act 2022) and published government dates; provided as-is with no warranty. Regional anniversary observance can vary locally. Verify critical deadlines with the relevant agency.
Output
Returns whether the supplied NZBN is valid, including format correctness and checksum verification. Likely includes a boolean validity flag and may include a reason or error detail if the number is invalid.
Example use cases
Supplier onboarding verification
“We're onboarding a new NZ supplier and they gave us NZBN 9429041234567 — can you verify that this is a valid New Zealand Business Number before we set them up in our system?”
Invoice fraud detection
“I just received an invoice claiming NZBN 9429000601517. Can you validate that NZBN to make sure it's a real, correctly formatted New Zealand business number?”
E-commerce merchant KYC
“A new merchant signed up with NZ business number 9429041096518 — is that a valid NZBN?”
Technical details
Endpoint
GEThttps://nzdata.zakwins.workers.dev/nz/validate/nzbn?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap ($0.001 USDC) programmatic check of a New Zealand Business Number without querying the full NZBN registry. Ideal for form validation, KYC pre-screening, or fraud detection pipelines where a format/checksum check is sufficient before deeper lookup.
Side effects
- Missing 'number' query parameter returns an error
- Malformed NZBN (wrong length, non-numeric) returns invalid result
- Network or worker timeout returns a 5xx error
- Invalid payment / x402 handshake failure returns 402 Payment Required
