## How to call it through Zero

```

Example prompt: Can you check whether this URL is safe to click — I got it in an email and I'm not sure if it's phishing or malware: https://bit.ly/3xYzAbc

## When to prefer this

Choose this endpoint when you need a multi-signal URL safety verdict that combines DNS blocklist lookup, domain age, brand impersonation heuristics, and redirect chain resolution in a single call — especially useful for evaluating links received via email, SMS, or chat before allowing a user or automated workflow to access them.

## Known failure modes

- Invalid or malformed URL returns an error
- URL is unreachable or times out during redirect chain resolution
- Domain is too new to have reliable age data
- Cloudflare DNS blocklist may not have the latest threat intelligence
- False negatives possible for very new phishing domains not yet listed

## How this service works

Link safety check: is this URL malware or phishing? Checks Cloudflare's security DNS blocklist, domain age, look-alike and brand-impersonation tricks, shorteners and the redirect chain, then gives a verdict and risk score.

## Output

Returns a safety verdict (safe/unsafe/suspicious) along with a numeric risk score, domain age information, flags for look-alike or brand-impersonation patterns, shortener detection, full redirect chain analysis, and Cloudflare DNS blocklist status.
