## 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-hcaptcha-54ab09fb
```

Example prompt: Can you check if stripe.com uses hCaptcha — I want to know before I plan our bot-protection migration strategy.

## When to prefer this

Use this endpoint when you need a lightweight, low-cost ($0.01) single-technology check specifically for hCaptcha presence on a website. Prefer it over general-purpose web crawlers or full technographic platforms when you need a fast yes/no answer with evidence, without paying for a full technology stack report. Ideal for high-volume sales prospecting, competitor audits, or pre-migration validation where hCaptcha is the specific technology of interest.

## Known failure modes

- Site is unreachable or returns a non-200 status — detection cannot be performed
- Site uses JavaScript-rendered hCaptcha that requires a browser runtime — HTML-only fetch may miss it
- Domain resolves but returns a redirect loop or bot-blocking page — incomplete fingerprint data
- Invalid or malformed domain provided — request fails with an error
- hCaptcha loaded via a third-party tag manager — may not appear in raw HTML

## How this service works

Does a website use hCaptcha? Fetches the page (homepage for a bare domain) and matches hCaptcha'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 boolean indicating whether the site uses hCaptcha, along with an evidence snippet from the HTML or response headers that triggered the match, and the technology category (security).
