## 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-4df1e8a1 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need to programmatically detect broken links on a specific web page, particularly for SEO auditing, pre-launch QA, or ongoing link health monitoring. Prefer this over generic scraping endpoints when the specific goal is identifying dead or invalid hyperlinks rather than extracting page content.

## Known failure modes

- Invalid or unreachable URL returns success: false
- Target site blocks crawling (returns error or empty data)
- maxLinks set too high may cause timeouts or incomplete results
- Malformed URL input causes request validation failure
- Payment failure on Base chain prevents request from completing

## How this service works

69 endpoints for data, content generation, and web scraping. Pay per request via x402 on Base chain.

## Output

Returns a JSON object with a 'success' boolean and a 'data' object containing details about the crawl, including information about broken or invalid links discovered on the target page.
