## 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 datavault-phone-number-validator-fe965108 -d '<json body>'
```

Example prompt: Can you check if the phone number +44 7911 123456 is valid? It's a UK number, so use GB as the country.

## When to prefer this

Use this endpoint when you need to validate or parse a phone number, especially for international numbers where country context matters. Prefer this over regex-only checks when you need authoritative validation including number type detection (mobile vs. landline) and country-specific formatting rules. Best suited for user onboarding flows, form validation, fraud prevention, or pre-call/SMS verification.

## Known failure modes

- Invalid or missing phone field returns an error response with success: false
- Unrecognized country code may result in failed validation or incorrect metadata
- Malformed phone number strings (e.g. letters, wrong length) return invalid result
- Payment failure via x402 protocol returns 402 status before processing
- Network timeout or upstream service unavailability returns 5xx error
