## 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 broken-link-checker-api-33b79f24 -d '<json body>'
```

Example prompt: Can you check https://www.mycompany.com/resources for any broken links and tell me which ones are dead?

## When to prefer this

Choose this endpoint when you need a quick, per-page broken link audit without setting up your own crawler. It is ideal for one-off QA checks, pre-launch validation, or periodic spot-checks on specific pages. For full-site crawls or continuous monitoring, a dedicated website crawler would be more appropriate.

## Known failure modes

- URL is unreachable or returns a non-200 status itself — may return an error or empty results
- Private/authenticated pages may not yield accurate results since the crawler has no session
- Very large pages with hundreds of links may take longer or time out
- JavaScript-rendered links may not be detected if the crawler uses static HTML parsing
- Rate limiting or bot blocking by the target site may cause incomplete results
