About

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.
