## 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 website-content-change-detector-2f65b3dd
```

Example prompt: Check if the content on https://example.com/announcements has changed recently — I want to know if anything on that page has been updated.

## When to prefer this

Use this endpoint when you need to programmatically detect whether the content of a specific webpage has changed, especially in automated monitoring or alerting workflows. It is well-suited for lightweight, per-URL polling tasks where you want a confidence-scored result and cache awareness without building your own diff infrastructure.

## Known failure modes

- Invalid or unreachable URL returns error response
- Missing required 'url' query parameter causes request failure
- Target website blocks crawlers, returning no useful diff data
- Cached response may not reflect very recent changes (check 'cached' field in _meta)
- Low confidence score indicates uncertain change detection result
