## 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 x402-onchainexpat-com-d06b8dfa -d '<json body>'
```

Example prompt: Can you check how trustworthy the website coinbase-airdrop2025.net is — I want a full trust score with WHOIS details, SSL validity, and any suspicious patterns that might suggest it's a scam?

## When to prefer this

Use this endpoint when you need to quickly assess whether a domain or website is legitimate before clicking a link, investing in a project, or interacting with an unknown service. Particularly useful for crypto-adjacent scam detection where newly registered domains and invalid SSL are red flags.

## Known failure modes

- Domain does not exist or cannot be resolved — returns error or null trust score
- Invalid URL or domain format supplied — returns validation error
- WHOIS lookup fails for certain TLDs or private registrations — partial result
- SSL data unavailable for HTTP-only sites — partial analysis returned
- Rate limit or payment failure — returns 402 or 429 error

## How this service works

Returns a trust score or assessment for a website.

## Output

Returns a trust score for the queried domain along with WHOIS registration data, SSL certificate analysis, and detected suspicious patterns that may indicate phishing, fraud, or other malicious activity.
