## 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-518bb093 -d '<json body>'
```

Example prompt: Can you compare the content of https://example.com/page-a and https://example.com/page-b and tell me what's different between them?

## When to prefer this

Use this endpoint when you need to programmatically compare the web content of two specific URLs — for example, detecting A/B test differences, verifying content parity between staging and production, or spotting changes between two competitor pages. Prefer this over scraping each URL separately when a structured diff or comparison output is needed in a single call.

## Known failure modes

- One or both URLs are unreachable or return non-200 status — success: false
- Invalid or malformed URL provided for urlA or urlB
- Target site blocks the crawler — success: false with error detail
- Payment fails or is insufficient — 402 response before processing
- Timeout on one or both URL fetches

## How this service works

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

## Output

A structured object with a success flag and a data object containing the comparison results between the two crawled URLs, including differences or similarity metrics between their content.
