## 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-microsoft-clarity-c111f345
```

Example prompt: Can you check if acme.com uses Microsoft Clarity for analytics? I need to know if they have it installed on their homepage.

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01) single-site check for Microsoft Clarity specifically. Prefer it over full technographic suites when you only need Clarity detection and want minimal overhead. It's ideal for per-record enrichment in sales pipelines, one-off competitor checks, or confirming analytics presence before migration. Use the bulk sibling endpoints when checking more than one domain at a time.

## Known failure modes

- Website is unreachable or returns non-200 status, resulting in an error or inconclusive result
- Site uses heavy JavaScript rendering so Clarity script is not present in the static HTML fetched
- Clarity snippet is loaded via a tag manager and not directly in the homepage HTML, causing a false negative
- Rate limiting or bot-blocking on the target site prevents page retrieval
- Domain input is malformed or missing, causing a request error

## How this service works

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

## Output

Returns a yes/no answer indicating whether Microsoft Clarity is detected on the website, along with an evidence snippet from the HTML or response headers that triggered the match, and the technology category label (analytics).
