## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nz-phone-number-validator-78bb8fdc
```

Example prompt: Can you check if '021 123 4567' is a valid New Zealand phone number?

## When to prefer this

Use this endpoint when you need to validate New Zealand phone numbers specifically and want a pay-per-call model with no subscription. Ideal for low-volume checks or ad-hoc validation where you don't want to integrate a full phone validation library. Prefer this over generic international phone validators when NZ-specific rules (including NZ number plan compliance) are required.

## Known failure modes

- Missing 'number' query parameter returns an error or empty result
- Non-NZ phone numbers may return invalid even if structurally valid internationally
- Ambiguous formats without country code may fail validation
- Payment not processed (x402 failure) results in 402 response with no data
- Malformed inputs (letters, special characters) return invalid status

## 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 validation result indicating whether the provided phone number is a valid New Zealand number, along with any parsed or normalised format information and details about the number type (mobile, landline, toll-free, etc.) if available.
