## 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 phone-number-parser-and-validator-d0c81866 -d '<json body>'
```

Example prompt: Can you parse and validate this phone number for me — +14155552671 — and tell me its country calling code, region, and whether it's a valid E.164 length?

## When to prefer this

Choose this endpoint when you need to normalize, validate, and extract metadata from international phone numbers in E.164 format — especially useful in signup flows, CRM data cleaning, SMS routing, and identity verification pipelines where standardized phone formatting is required.

## Known failure modes

- Phone number missing leading + and country code — returns parse error or invalid format
- Number too short or too long to pass E.164 length validation — returns invalid length error
- Unrecognized or non-existent country calling code — returns unknown region
- Malformed input with non-numeric characters — returns format error
- Empty or null input — returns missing parameter error

## How this service works

Parse a phone number to E.164, detect its country calling code and region, and validate length against the E.164 standard. Provide a number with a leading + and country code.

## Output

Returns the E.164-normalized phone number, the detected country calling code (e.g. 1 for US/Canada, 44 for UK), the geographic region or country name, and a boolean or status indicating whether the number's length is valid per E.164 specifications.
