## 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 e-164-phone-number-formatter-validator-25fb37f5 -d '<json body>'
```

Example prompt: Can you normalize this phone number to E.164 format and tell me its country and line type — the number is '(415) 555-0132' and it's a US number?

## When to prefer this

Use this endpoint when you need to normalize phone numbers to E.164 before passing them to a paid SMS/calling API, when deduplicating leads by phone, or when validating user-submitted phone input across international formats. Prefer this over rolling your own regex or using a general-purpose library when you also need line-type classification and country identification in a single call.

## Known failure modes

- Malformed or completely unrecognizable number string returns a validation error
- Missing country code on a national-format number with no default-country hint may fail to resolve
- Ambiguous number formats for some regions may produce incorrect country assignment
- Numbers that look structurally valid but are unallocated may return unknown line type

## How this service works

Parses loosely formatted phone number input and returns its E.164 standard representation, country, and line type, with a default-country hint for numbers missing a country code. Built for lead deduplication, SMS delivery systems, and validation steps that reject malformed numbers before they hit a paid messaging API.

## Output

Returns the E.164 formatted phone number (e.g. +14155550132), the detected country (ISO code), and the line type (e.g. mobile, landline, VoIP), enabling downstream validation or routing decisions.
