## 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 irantools-iranian-landline-phone-number-validator-fb760dfa -d '<json body>'
```

Example prompt: Can you check if '02112345678' is a valid Iranian landline phone number?

## When to prefer this

Use this endpoint when you need to validate Iranian landline (fixed-line) phone numbers specifically, as opposed to mobile numbers. It is ideal for form validation, CRM data quality checks, fraud detection pipelines, or any workflow that ingests user-supplied Iranian phone numbers and needs to confirm they follow valid Iranian landline formatting and area code conventions. Prefer this over generic regex checks because it understands Iranian-specific area codes and regional number structures.

## Known failure modes

- Missing 'value' field in request body returns validation error
- Non-string input may cause parsing error
- Empty string returns invalid result
- Network timeout on Cloudflare Workers edge
- Payment failure via x402 if USDC balance insufficient
