## How to call it through Zero

```sh
zero fetch --capability does-site-use-google-fonts-18968268
```

Example prompt: Can you check if shopify.com uses Google Fonts on its homepage? I need to know for a competitor font stack analysis.

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01) single-domain check for Google Fonts usage specifically. Prefer this over general technographic platforms when you need a lightweight, programmatic yes/no answer with evidence for sales qualification, competitor research, or pre-migration audits. If you need to check multiple domains at once, look for a bulk variant of this endpoint on the same provider.

## Known failure modes

- Domain is unreachable or returns an error — endpoint cannot fetch the page and may return an error or inconclusive result
- Site uses Google Fonts only on non-homepage routes — the check is limited to the homepage and may return false negative
- Google Fonts is loaded via JavaScript after page load (client-side only) — server-side HTML fingerprinting may miss it
- Rate limiting or bot protection on the target domain blocks the fetch
- Invalid or malformed domain input causes request failure

## How this service works

Does a website use Google Fonts? Fetches the page (homepage for a bare domain) and matches Google Fonts's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (fonts). 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 Fonts is detected, along with the matching evidence snippet found in the HTML or response headers, and the technology category label 'fonts'.
