## 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-vue-js-381ad130
```

Example prompt: Can you check whether stripe.com uses Vue.js on their frontend — I want to know before our sales call with them?

## When to prefer this

Choose this endpoint when you need a fast, low-cost, single-domain check for Vue.js specifically. Ideal for sales enrichment pipelines, competitor research, or migration audits where you need Vue.js detection with evidence snippets. Use the bulk sibling endpoints when checking more than one domain at a time.

## Known failure modes

- Domain is unreachable or returns a non-200 response, resulting in an error or inconclusive result
- Site uses client-side-only Vue.js rendering that is not present in the initial HTML response, potentially returning a false negative
- Rate limiting or bot protection on the target site may block the fetch
- Bare domain redirects to a non-standard homepage that is not crawled

## How this service works

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

## Output

Returns a yes/no boolean indicating Vue.js usage, an evidence snippet from the HTML or response headers that matched Vue.js fingerprints, and a category label ('framework'). Useful for programmatic technographic enrichment at $0.01 per check.
