## 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 x402-zadenworks-broken-link-checker-d29e57c5 -d '<json body>'
```

Example prompt: Check these three pages for broken links and tell me which ones have 404s or other errors: https://mysite.com/, https://mysite.com/about, and https://mysite.com/blog — include external links too.

## When to prefer this

Choose this endpoint when you need a quick, per-page broken link audit with scored results and severity ranking, especially when you want no account setup and pay-per-call USDC billing. Prefer it over full-site crawlers when you already know which specific pages to check (up to 5). If you want a combined audit including SEO and accessibility in one call, use /audit instead.

## Known failure modes

- Invalid or unreachable URLs return errors per entry
- Exceeding 5 URLs in the array may be rejected
- Pages behind authentication or bot-blocking may not be crawlable
- Timeout if target pages are very slow to respond
- Malformed URL strings in the array cause validation errors

## How this service works

Fourteen pay-per-call web tools for AI agents, billed in USDC on Base with no account or API key. START WITH /audit -- one call returns a complete page health check (SEO + structured data + accessibility, optionally plus links and sitemap) with a single score and one worst-first findings list. The parts are also sold individually. SITE AUDIT: /seo (on-page SEO and meta tags), /links (broken links), /sitemap (robots.txt and XML sitemap crawlability), /structured (JSON-LD and social preview tags), /a11y (WCAG accessibility) -- each scored 0-100 with a prioritised issue list. READING: /read (clean markdown), /snap (screenshot, PDF or rendered HTML), /tables (every HTML table as structured JSON), /verify (does a claim actually appear on this page). MONITORING: /watch (has this page changed), /compare (what differs between two pages). Plus /rank (best x402 service for a task) and /batch (several operations behind one payment).

## Output

Returns a per-page results array where each entry includes a letter grade (e.g. A-), a numeric score 0-100, a summary sentence, the source URL, total links checked, number of broken links, and a list of broken link objects each with URL, HTTP status code, and severity level.
