## How to call it through Zero

```sh
zero fetch --capability does-site-use-perimeterx-790536f4
```

Example prompt: Can you check whether stripe.com uses HUMAN (PerimeterX) for bot protection, and show me whatever evidence snippet you find?

## When to prefer this

Use this endpoint when you need a lightweight, per-site check specifically for HUMAN (PerimeterX) bot protection technology. It is ideal for sales technographic enrichment, competitive intelligence, and pre-migration audits where you need a single-technology yes/no answer with evidence rather than a full technology stack scan.

## Known failure modes

- Domain not reachable or returns non-200 response — detection cannot proceed
- Site uses bot protection that blocks the crawler — may return false negative
- Ambiguous or obfuscated PerimeterX deployment may not match known fingerprints
- Invalid or malformed domain input returns an error
- Rate limiting or network timeout on the target site

## How this service works

Does a website use HUMAN (PerimeterX)? Fetches the page (homepage for a bare domain) and matches HUMAN (PerimeterX)'s fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (security). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.

## Output

Returns a yes/no boolean indicating whether HUMAN (PerimeterX) is detected on the target site, along with the specific HTML or response header evidence snippet that triggered the match and the technology category (security).
