```

Example prompt: Can you compare these two product pages for me — https://store-a.com/product/widget and https://store-b.com/product/widget — and tell me how they differ in content?

## When to prefer this

Choose this endpoint when you need to programmatically compare the content of two specific web pages without setting up auth or subscriptions — ideal for one-off competitive analysis, duplicate content detection, or A/B page audits paid per-request in USDC via x402.

## Known failure modes

- One or both URLs are unreachable or return non-200 status, resulting in a failure response
- URLs point to login-gated or bot-protected pages that cannot be scraped
- Invalid or malformed URLs cause request rejection
- Payment via x402 not completed, blocking access to the endpoint
- Response schema is loosely defined so structured diff depth may vary
