## 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 creator-desk-broken-link-checker-f6f3a3fa -d '<json body>'
```

Example prompt: Check these URLs for me and tell me which ones are broken or returning errors: https://myblog.com/post-1, https://myblog.com/old-page, and https://myblog.com/contact

## When to prefer this

Choose this endpoint when you need to programmatically verify the reachability of a known list of up to 20 URLs at once, especially in automated content pipelines, pre-publish audits, or SEO workflows. It is ideal for agents that already have a concrete list of URLs to check rather than needing to crawl or discover links. Prefer this over a full site crawler when the URL list is bounded and explicit.

## Known failure modes

- Private/localhost URLs or non-port-443 targets are rejected with an error
- URLs returning connection timeouts will be flagged as broken with a null status
- Invalid URL formats will be rejected at input validation
- Non-HTTPS URLs are rejected
- Batch limit of 20 URLs exceeded returns a validation error
- Sites with aggressive bot-blocking may return misleading non-error status codes

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON array of per-URL results, each containing: ok (boolean), url (original), broken (boolean), status (HTTP code), final_url (after redirects), redirects (count), error_code, and latency_ms. Also returns aggregate counts: broken, healthy, checked, plus a timestamp and version.
