## 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 cheetah-security-url-domain-reputation-check-cb2615d9 -d '<json body>'
```

Example prompt: Can you check whether this URL is safe to click — https://totally-legit-bank-login.ru/secure — and tell me the risk score and whether it's flagged as phishing or malware?

## When to prefer this

Use this endpoint when you need a single, per-call reputation check on a URL or domain with pay-per-use pricing (no subscription required). Prefer it over batch endpoints when checking one link at a time, and over generic search when you need a structured verdict plus risk score rather than a web search result. Especially suited for AI agents that need to gate user-submitted URLs in real time.

## Known failure modes

- Missing or malformed URL input returns a validation error
- Unresolvable or newly registered domains may return low-confidence results
- Rate limiting or payment failure (x402) may block the call
- Private/internal IP addresses or localhost URLs may be rejected
- Very new or uncategorized domains may return an ambiguous verdict
