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

Example use cases
Political statement fact-checking
“I just saw a politician claim that 'unemployment dropped by 40% last year' — can you verify if that's actually true, checking against at least 3 sources?”
News headline accuracy check
“There's a viral headline saying 'Scientists have discovered a cure for Alzheimer's disease' — can you verify whether this claim is accurate?”
Product advertisement validation
“This supplement brand claims that 'their product increases energy levels by 300%' — can you check if that claim holds up against the evidence?”
Technical details
Endpoint
POSThttps://scravfly.vercel.app/api/crawl/verifyWhen to prefer
Choose this endpoint when you need to programmatically verify a specific factual claim against multiple web sources, especially within an automated agent pipeline that handles x402 micropayments on Base chain. It is well-suited for fact-checking workflows where you want a structured true/false result with supporting data, rather than a raw web search or scrape.
Side effects
- Empty or malformed claim string returns failure
- Invalid sources count (non-number) causes request rejection
- Network timeout if sources take too long to retrieve
- Ambiguous or too-short claim may return inconclusive result
- Rate limiting or payment failure via x402 protocol
