## 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-bing-uet-2fef6e9d
```

Example prompt: Can you check whether shopify.com has Microsoft Advertising UET installed on its homepage and show me the evidence snippet?

## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.01) single-domain check for Microsoft Advertising UET specifically. Prefer it over generic technographic platforms when you want per-call pricing without a subscription, or when building a pipeline that checks one technology at a time. If you need to check multiple domains at once, look for the bulk variant on the same provider.

## Known failure modes

- Site is unreachable or returns non-200 status — result may be indeterminate or error
- Site blocks crawlers with bot-detection (Cloudflare, etc.) — fingerprint may not be found even if UET is present
- UET loaded asynchronously or via tag manager may not appear in static HTML — false negative possible
- Invalid or malformed domain input — endpoint returns error
- Rate limiting or network timeout on the target domain — incomplete fetch

## How this service works

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

## Output

Returns a yes/no boolean indicating whether Microsoft Advertising UET is detected on the site, along with the matching evidence snippet (e.g., the HTML or header fragment containing UET fingerprints) and the technology category label ('advertising').
