## 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 scrapfly-crawl-compare-side-by-side-web-page-comparison-7e914715 -d '<json body>'
```

Example prompt: Can you compare the content of these two pages for me — https://example-site-a.com/product and https://example-site-b.com/product — and tell me what's different between them?

## When to prefer this

Use this endpoint when you need to programmatically compare the live content of two web pages — for example, tracking changes between a competitor's page and your own, verifying that a page migration preserved content, or detecting drift between two versions of a document. Prefer this over manual scraping + diffing two separate endpoints when you need a single atomic comparison call.

## Known failure modes

- One or both URLs are unreachable or return non-200 status — success: false
- URLs point to bot-protected or heavily JavaScript-rendered pages that cannot be scraped
- Malformed or missing urlA / urlB parameters — validation error
- Payment failure on Base chain — 402 payment required
- Timeout if one or both pages are very slow to load

## How this service works

69 endpoints for data, content generation, and web scraping. Pay per request via x402 on Base chain.

## Output

Returns a JSON object with a success boolean and a data object containing the comparison results between the two crawled pages, including structural or content differences extracted from both URLs.
