Fact Checker — Verify Claims with Web Evidence

One of the ways to connect Fact Checker — Verify Claims with Web Evidence

AI-powered fact-checking API for AI agents. Verify any factual claim with web evidence: searches multiple sources, assesses credibility, provides supporting/contradicting URLs, and returns confidence level (confirmed/likely/unverified/false). Tools: research\_check\_fact. Use this before repeating claims, for content moderation, or building trustworthy AI systems. Essential for reducing hallucinations. IMPORTANT: For web search without fact assessment, use web\_search\_query. Returns: {verdict, confidence, sources\[], evidence\[]}. No API key required — x402 micropayment $0.005/call on Base L2.

Verify factual claims by searching the web and returning relevant evidence snippets, with pay-per-call payment via x402.
