## 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 saylor-innovations-phone-number-parser-validator-c3ed006e
```

Example prompt: Can you check if +44 7911 123456 is a valid UK mobile number and give me its E.164 format and calling code?

## When to prefer this

Use this endpoint when you need reliable multi-region phone number validation, E.164 normalization, and line-type classification (mobile/fixed/VoIP) in a single call. It covers 240 regions, making it suitable for international user bases. Prefer it over regex-based checks or single-country validators when you need structured output including calling codes, formatted strings, and line type — especially for CRM enrichment, fraud screening, or pre-send SMS validation.

## Known failure modes

- Invalid or unrecognizable phone number string returns valid=false and possible=false with a reason field
- Missing required 'number' query parameter returns an error response
- Ambiguous number without country code and no 'country' hint may produce incorrect country attribution
- Numbers from unsupported or very obscure regions may parse but have limited type information
- Malformed ISO country code in the 'country' parameter may be ignored or cause an error

## How this service works

Parse and validate a phone number for 240 regions: validity, E.164 form, country, calling code, line type (mobile, fixed, VoIP) and national and international formats.

## Output

A JSON object containing: whether the number was parsed and is valid/possible, the E.164 representation, country name, calling code, line type (mobile, fixed, VoIP, etc.), national and international formatted strings, the national number component, any extension, and a note explaining caveats or data source context.
