## 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 workbot1-oddsys-org-phone-number-validation-e3a35132 -d '<json body>'
```

Example prompt: Can you validate this phone number and tell me if it's real, what country it's from, and whether it's a mobile or landline — the number is +1 (415) 555-0182? Also give me the E.164 and international formats.

## When to prefer this

Choose this endpoint when you need authoritative phone number validation and normalization powered by Google libphonenumber, especially when you need multi-format output (E.164, international, national), line-type classification (mobile/VoIP/fixed), or batch processing of up to 100 numbers. Prefer over regex-based validators when correctness and international coverage matter.

## Known failure modes

- Invalid or unparseable phone number string returns validity=false with no format fields
- Batch exceeding 100 numbers may be rejected or return an error
- Ambiguous numbers without a country hint may fail to parse correctly
- Numbers with non-standard characters or formatting may cause parse errors
- Missing country hint for local-format numbers (e.g. 07911...) may produce incorrect country assignment

## How this service works

Validate and normalize phone numbers (Google libphonenumber): validity, E.164/international/national formats, country, region, and line type (mobile/fixed/VoIP). Single number or batches up to 100.

## Output

Returns a structured result per number including: validity boolean, E.164 format (e.g. +14155550182), international format, national format, country code (ISO), region, and line type (mobile, fixed_line, voip, etc.). For batch requests, returns one result object per input number.
