## 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 nojunk-safety-gate-site-url-safety-check-1bd7ac57 -d '<json body>'
```

Example prompt: Before you open that link or proceed with the payment, run a safety check on https://quickpay-crypto.net — I want to know if it's flagged as phishing, suspicious, or safe, with a clear ALLOW, CAUTION, or BLOCK verdict.

## When to prefer this

Use this endpoint when an AI agent needs a quick, structured ALLOW/CAUTION/BLOCK verdict on a website URL or domain before opening a link, navigating to a page, or authorising an x402 payment to a web-based seller. It is purpose-built for agent pre-action safety gates and returns a machine-readable verdict rather than raw reputation scores, making it ideal for automated decision pipelines without manual review.

## Known failure modes

- Missing or malformed URL input returns a validation error
- Unknown or very new domains may return CAUTION due to insufficient data
- Third-party security database outages may degrade verdict accuracy
- Extremely obscure TLDs may not resolve or have registration data
- Payment failure (x402) prevents the check from running

## How this service works

Yes/no safety verdicts an agent runs before it acts: before sending funds (/wallet), buying a token (/token), opening a link (/site) or paying an x402 seller (/x402). Every answer has safe (true/false), verdict (ALLOW, CAUTION, BLOCK) and a one-line reason.

## Output

Returns a JSON object with: `safe` (boolean), `verdict` (ALLOW, CAUTION, or BLOCK), `check` (always 'site'), `flags` (array of issue tags), `reason` (one-line human-readable explanation), `target` (normalised domain), `checked_at` (ISO timestamp), and a legal disclaimer noting the automated nature of the check.
