## How to call it through Zero

zero fetch --capability does-site-use-json-ld-2a4c1962
```

Example prompt: Can you check if shopify.com uses JSON-LD structured data on its homepage and show me any evidence you find?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01) single-domain check for JSON-LD structured data presence without needing to parse the full page yourself. Ideal for sales prospecting, bulk technographic surveys (calling one domain at a time), SEO audits, and pre-migration planning where a binary yes/no with evidence is sufficient. Prefer this over full HTML scrapers when you only need JSON-LD detection, not general page content.

## Known failure modes

- Domain is unreachable or returns a non-200 status — endpoint may return an error or a 'no' result with no evidence
- Website blocks crawlers via robots.txt or returns a CAPTCHA — fingerprint matching may fail
- Page loads JSON-LD dynamically via JavaScript — server-side detection may miss client-rendered structured data
- Malformed or non-standard JSON-LD may not match expected fingerprints
- Rate limiting or network timeouts may result in failed checks

## How this service works

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

## Output

Returns a yes/no flag indicating whether JSON-LD structured data was detected on the website's homepage, along with the matching evidence snippet from the HTML or response headers, and a category label (meta). The response reflects the actual live state of the page at time of request.
