How this service works
69 endpoints for data, content generation, and web scraping. Pay per request via x402 on Base chain.
Output
A JSON object with a success boolean and a data object containing the comparison results — likely including extracted content, structural differences, or textual diffs between the two provided web pages.
Example use cases
Competitor product page comparison
“Compare the pricing and features listed on https://competitorA.com/pricing and https://competitorB.com/pricing and tell me what's different between them.”
Before and after site update check
“I just updated my landing page — can you compare the old cached version at https://web.archive.org/web/20240101/https://mybrand.com and the current live page at https://mybrand.com to show me what changed?”
Duplicate content detection
“Check if these two blog posts are basically the same content or genuinely different: https://blog.site.com/article-a and https://blog.site.com/article-b.”
Technical details
Endpoint
POSThttps://scravfly.vercel.app/api/crawl/compareWhen to prefer
Use this endpoint when you need to programmatically compare the content of two publicly accessible web pages — such as detecting changes over time, comparing competitor pages, or validating content parity. Prefer this over manual scraping + diffing when you want a single API call to handle both fetching and comparison. It is well-suited for competitive intelligence, QA workflows, and change monitoring tasks.
Side effects
- One or both URLs are unreachable or return non-200 status — success: false
- URLs point to pages requiring authentication or bot-blocking — scrape may fail or return partial content
- Malformed or non-string URL inputs — validation error
- Rate limiting or payment failure via x402 — request rejected
- Pages are identical — comparison returns empty or null diff
