Example prompt: Compare these two web pages for me and tell me what's different: https://example.com/product-old and https://example.com/product-new

## When to prefer this

Use this endpoint when you need to programmatically compare the content of two specific web pages without setting up authentication or a subscription — ideal for competitive analysis, A/B page audits, changelog detection, or price comparison between two product URLs. Pay-per-use at $0.25 USDC makes it suitable for on-demand agent workflows.

## Known failure modes

- Invalid or unreachable URL returns error in data field with success: false
- One or both URLs timeout during scraping
- Payment of 0.25 USDC not fulfilled via x402 results in 402 response
- Malformed request missing urlA or urlB returns validation error
- URL behind authentication or bot protection cannot be scraped

## How this service works
