## 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 bytemine-web-page-content-diff-e10271f9 -d '<json body>'
```

Example prompt: Check https://example.com/pricing against its last snapshot and tell me what lines have been added or removed since it was last crawled.

## When to prefer this

Use this endpoint when you need to detect what specifically changed on a webpage between the current moment and a prior crawl. It is ideal for monitoring tasks, competitive intelligence, or compliance workflows where precise line-level diff output (added/removed) matters more than just knowing a page changed. Prefer this over a plain scraper when you already have a baseline snapshot and want structured change data rather than raw HTML.

## Known failure modes

- No previous snapshot exists for the URL — diff cannot be performed
- URL is inaccessible or returns a non-200 status — crawl fails
- Page content is dynamically rendered and differs from the stored snapshot due to JavaScript — may produce noisy diffs
- Invalid or malformed URL input — request rejected
- Rate limit or credit exhaustion — request denied
