## 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 scrapfly-broken-link-crawler-d7af78a1 -d '<json body>'
```

Example prompt: Can you crawl https://example.com and find all the broken links on that page, checking up to 50 links?

## When to prefer this

Choose this endpoint when you need to programmatically detect broken or dead links on a specific webpage without building your own crawler. It is ideal for automated SEO audits, pre-launch QA checks, or content management workflows where link integrity matters. Prefer it over general-purpose scraping endpoints when the specific goal is link validation rather than content extraction.

## Known failure modes

- Invalid or unreachable target URL returns success: false
- Target site blocks the crawler, resulting in incomplete or empty results
- maxLinks set too low may miss broken links deeper in the page
- Network timeouts on slow-loading target pages
- Relative links may not be resolved correctly if the base URL is ambiguous
