## 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 foundry-phone-number-validator-44d2552d -d '<json body>'
```

Example prompt: Can you validate the phone number +44 20 7946 0958 and tell me if it's valid, what format it should be in, and what region and timezone it belongs to?

## When to prefer this

Use this endpoint when you need to validate, normalize, or enrich a single phone number — especially when you need E.164 formatting for storage, carrier identification before messaging, or timezone/region lookup tied to a phone number. Prefer this over generic regex validation when accurate type classification (mobile vs landline) or carrier data is required.

## Known failure modes

- Invalid or missing phone number input returns valid: false and possible: false
- Numbers without a country code prefix and no region hint may fail to parse
- Carrier data may be null for some number ranges or countries
- Render cold-start may cause occasional latency spikes on first call
- Malformed input (non-numeric garbage) may return an error or invalid result
