## 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 hubvibe-site-audits-page-monitor-snapshot-16c6aebb -d '<json body>'
```

Example prompt: Take a snapshot of https://example.com/pricing right now and save it as the baseline so we can check later whether anything on that page has changed.

## When to prefer this

Use this endpoint as the first step in a two-step page monitoring workflow: call snapshot once to establish a baseline, then call monitor.check repeatedly to detect changes. Prefer this over general web scraping tools when your goal is change detection rather than data extraction. This is the correct starting point any time you want to set up a 'has this page changed?' monitor for a specific URL.

## Known failure modes

- Invalid or unreachable URL returns an error (non-200 HTTP response or DNS failure)
- URL uses an unsupported scheme (not http or https)
- Page requires authentication or returns a 403/401, resulting in an empty or partial snapshot
- Timeout if the target page is very slow to respond
- Snapshot storage failure if the service is temporarily unavailable

## How this service works

Website change monitoring, step one: fetch a page and store it as the baseline to compare against later. Use it to watch pricing pages, terms, job boards or competitors. Input: url. Then call monitor.check to learn whether and how it changed.

## Output

Returns a confirmation that the page has been fetched and stored as a baseline snapshot, along with metadata needed to reference this snapshot later when calling monitor.check to detect changes.
