Example prompt: Can you check whether linear.app uses Plausible Analytics on their website?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01) single-technology check specifically for Plausible Analytics on a given domain. Ideal for sales enrichment pipelines, competitive intelligence, or migration verification where you only need to know about Plausible and not a full technology stack scan. Prefer this over full-stack technographic services when cost and simplicity matter and Plausible is the only technology of interest.

## Known failure modes

- Target website is unreachable or returns non-200 status — check may fail or return inconclusive result
- Website uses server-side rendering or delayed script injection — Plausible fingerprint may not be present in initial HTML fetch
- Website blocks crawlers or headless fetches — could result in false negative
- Domain resolves but homepage redirects heavily — may not detect Plausible on the final page
- Rate limiting or network timeout from the target domain

## How this service works

Does a website use Plausible? Fetches the page (homepage for a bare domain) and matches Plausible'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 Plausible Analytics was detected on the target website, along with the evidence snippet (e.g. matching HTML script tag or response header) and the technology category label (analytics).
