three.ws Real-Time Fact Checker — sourced verdicts with cryptographic attestations you can audit, backed by a published accuracy benchmark. Submit a claim and receive a sourced verdict (supported/contradicted/mixed/insufficient) from live web search and LLM analysis: cited sources, authority weights, confidence score, cost breakdown, and a SHA-256 attestation. 3 free checks/day per IP (the same real chain, marked lane:"free") before the $0.10 base x402 price per check on Base or Solana USDC. Strictness controls how aggressively low-authority sources are downweighted. See /fact-check for the live benchmark.
