## How to call it through Zero

```sh
zero fetch --capability phone-number-normalizer-3b0f55d6
```

Example prompt: Can you normalize the phone number '2125551234' to international format — it's a US number, so use US as the default country?

## When to prefer this

Choose this endpoint when you need lightweight, low-cost phone number normalization without a full identity or carrier lookup. Ideal for sanitizing user-submitted phone numbers before storage or communication, especially when country context can be provided explicitly.

## Known failure modes

- Invalid or unparseable phone number string returns an error
- Missing required 'phone' query parameter returns a validation error
- Ambiguous number without a default_country may fail or return incorrect formatting
- Unsupported country codes may not resolve correctly

## How this service works

Normalize caller-supplied phone numbers into international-style formatting using explicit country context when needed.

## Output

Returns the phone number reformatted into international style (e.g. E.164 or +CC format), resolving local notation using the supplied default country when the number lacks a country prefix.
