## How to call it through Zero

```sh
zero fetch --capability agentstall-za-normalize-phone-number-715597ec
```

Example prompt: Can you normalize and validate this South African phone number for me — 082 123 4567 — and tell me if it's a mobile or landline and what the E.164 format is?

## When to prefer this

Choose this endpoint when you need to validate, normalize, or classify South African phone numbers specifically. It handles local formats (082 xxx, 011 xxx, +27 xx) and returns both E.164 and national formats with line-type classification in a single call. Prefer this over generic international phone validators when your use case is specifically South African numbers and you are already operating within the AgentStall ZA x402 payment ecosystem.

## Known failure modes

- Missing 'number' query parameter returns 402 or 400 error
- Unpaid call returns HTTP 402 with PAYMENT-REQUIRED header (x402 v2 flow not completed)
- Non-South African numbers may return valid:false or an error
- Malformed or nonsensical input strings may return valid:false
- Network errors on Cloudflare Workers edge may return 5xx

## How this service works

South African phone number formatting and classification: converts an SA number in any common format to international +27 (E.164) and local formats, and says whether it is mobile, landline (with area for major cities), toll-free, VoIP or premium-rate. Useful for cleaning contact lists, SMS and WhatsApp messaging, and form validation.

## Output

A JSON object containing: 'e164' (E.164 international format, e.g. '+27821234567'), 'national' (South African national format, e.g. '082 123 4567'), 'type' (line type, e.g. 'mobile' or 'landline'), and 'valid' (boolean indicating whether the number is valid).
