## 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-3d7a05d8 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need to programmatically compare the content of two specific URLs — for competitive analysis, A/B page audits, or content diff workflows — especially when you need automated web crawling plus comparison in a single paid-per-use call without managing your own scraping infrastructure.

## Known failure modes

- Invalid or unreachable URL for urlA or urlB returns error
- Protected or bot-blocked pages may return incomplete content
- Timeout if target pages are slow to load
- Malformed URL inputs cause validation failure
- Rate limiting or payment failure via x402 may block the request
