## When to prefer this

Use this endpoint when you need to validate a New Zealand bank account number format and checksum before processing a payment or storing account details. It is a cheap ($0.001 USDC), pay-per-call service requiring no subscription. Prefer this over building your own NZ bank account validation logic when operating in a New Zealand financial context.

## Known failure modes

- Missing 'number' query parameter returns an error
- Malformed or non-NZ-format account number may return invalid with no detailed reason
- Empty response example in schema means exact error structure is unknown
- Service may be unavailable if the upstream Cloudflare Worker is down
- Payment failure via x402 if USDC balance is insufficient

## 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 a JSON object indicating whether the provided New Zealand bank account number is valid, likely including a validity flag and possibly parsed components such as bank code, branch, account number, and suffix.
