## 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 argentine-phone-number-normalizer-8f03d72b -d '<json body>'
```

Example prompt: Normalize this Argentine phone number for me — 011 15 1234-5678 — and give me the WhatsApp link and E.164 format I should use.

## When to prefer this

Use this endpoint when you need to normalize, validate, or reformat Argentine phone numbers specifically — especially when building WhatsApp integrations, CRM pipelines, or communication tools targeting Argentina. It handles the notoriously complex Argentine numbering system (15/9 mobile prefixes, Buenos Aires 011 codes) automatically, which generic international phone libraries often get wrong.

## Known failure modes

- Invalid or unrecognizable Argentine phone number returns valid: false
- Number outside Argentine numbering plan may fail validation
- Malformed input strings exceeding 40 characters may be rejected
- Ambiguous numbers (e.g. missing area code) may produce incorrect area code extraction
