## 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 agentstall-za-official-domain-check-254a950f
```

Example prompt: Can you check whether 'sars-refund-portal.co.za' is an official South African Revenue Service website or a possible impersonation/phishing site?

## When to prefer this

Use this endpoint when you need to verify whether a URL or domain is legitimately associated with a known South African organisation — particularly government bodies (like SARS), state-owned enterprises, or major financial institutions. It is purpose-built for the South African context and is especially valuable for phishing detection, fraud prevention workflows, and due-diligence checks before interacting with an unfamiliar South African website.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error
- Unpaid call returns HTTP 402 with PAYMENT-REQUIRED header
- Unknown or very new domains may return low-confidence or inconclusive results
- Domains not associated with any recognised South African organisation may return no impersonation signals
- Malformed URLs may fail to parse correctly

## How this service works

Phishing and fake-website check for Africa: compares a link or domain with the official domains of about 130 tax authorities (SARS, KRA, FIRS, GRA), central banks, government services, banks, mobile money (M-Pesa, MTN MoMo, OPay) and telecoms in South Africa and 10 other African countries, and flags lookalike domains, typosquats, brand names in unofficial domains and newly registered domains.

## Output

Returns a JSON object with a risk level (e.g. 'high'), a verdict (e.g. 'possible-impersonation'), an array of signals explaining what triggered the flag (such as brand name usage), and a list of the real official domains for any organisation being potentially impersonated.
