## How to call it through Zero

```sh
zero fetch --capability does-site-use-recaptcha-b93422da
```

Example prompt: Can you check whether shopify.com uses reCAPTCHA on its homepage — I want to know if they rely on it for bot protection before we plan our migration.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01) single-technology check specifically for reCAPTCHA presence on a website. It is ideal for sales prospecting workflows, competitor technographic profiling, or pre-migration audits where you need a binary yes/no with supporting evidence rather than a full tech-stack scan. Prefer sibling endpoints for other specific technologies (e.g. WordPress, Shopify, Matomo).

## Known failure modes

- Website is unreachable or returns a non-200 status, resulting in an error or inconclusive result
- Site uses JavaScript-rendered reCAPTCHA that is not present in raw HTML, potentially causing false negatives
- Domain redirects to a page that obscures reCAPTCHA fingerprints
- Rate limiting or bot-blocking by the target site prevents fetching
- Invalid or malformed domain input causes request failure

## How this service works

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

## Output

Returns a yes/no answer indicating whether reCAPTCHA was detected, along with the evidence snippet from the HTML or response headers that triggered the match, and a technology category label (security).
