## 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 invoket-phone-number-validation-5cee230a
```

Example prompt: Is +33612345678 a valid phone number, and if so, what country and type is it — mobile or landline?

## When to prefer this

Choose this endpoint when you need lightweight, per-call phone number validation without maintaining an account or API key, especially in autonomous agent pipelines that can pay per call via x402 stablecoin. Ideal for one-off validations, serverless workflows, or when you want to avoid subscription overhead. Backed by libphonenumber for reliable international coverage.

## Known failure modes

- Invalid or unparseable phone number string — returns valid: false with no format data
- Missing required query parameter — returns 400 Bad Request
- Payment not provided or insufficient — returns 402 Payment Required (x402)
- Rate limiting or network timeout — returns 429 or 5xx
- Ambiguous number without country context — may return incorrect country classification
