## 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 does-site-use-optimizely-7c8b605b
```

Example prompt: Can you check if acme.com uses Optimizely for A/B testing? I want to know before my sales call with them.

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01) single-technology check specifically for Optimizely on a given domain — ideal for sales prospecting, competitive research, or pre-migration audits where you only need Optimizely detection and not a full technology stack scan.

## Known failure modes

- Site is unreachable or returns non-200 response — detection cannot be performed
- Site uses heavy JavaScript rendering that hides Optimizely loading — may return false negative
- Rate limiting or bot blocking by the target domain — may return inconclusive result
- Bare domain redirect loops or non-standard homepage URLs — may fail to fetch content

## How this service works

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

## Output

Returns a yes/no boolean indicating whether the site uses Optimizely, an evidence snippet (the matching HTML or header content that triggered the fingerprint), and a technology category label ('ab-testing').
