## 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-google-analytics-4-3f1a4b03
```

Example prompt: Can you check if shopify.com uses Google Analytics 4 — I want to know whether they've migrated to GA4 and see any evidence snippet from their page?

## When to prefer this

Use this endpoint when you need a quick, per-domain check for Google Analytics 4 presence without running a full tech stack audit. It is ideal for sales teams enriching CRM records one account at a time, for migration audits verifying GA4 deployment, or for competitive research into a specific company's analytics tooling. For bulk checks across many domains simultaneously, prefer the corresponding bulk sibling endpoint.

## Known failure modes

- Domain does not resolve or is unreachable — request fails with network error
- Site uses bot-detection or blocks automated fetches — may return false negative (no GA4 detected even if present)
- GA4 loaded via server-side tag manager or tag injection after page load — may not be detectable in static HTML
- Malformed or bare domain input without proper formatting — may cause fetch failure
- Rate limiting or timeout on the target site — returns error or inconclusive result

## How this service works

Does a website use Google Analytics 4? Fetches the page (homepage for a bare domain) and matches Google Analytics 4'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 boolean indicating whether Google Analytics 4 is detected on the target website, along with an evidence snippet (the matching HTML fragment or header value that triggered the fingerprint match) and the technology category label ('analytics').
