Verity

clawdio777/verity

Connects Claude to a live fact-checking API that returns structured verdicts (CURRENT, OUTDATED, DISPUTED, UNVERIFIABLE) with confidence scores and supporting sources. Exposes four tools: verity_verify for single claims, verity_deep_check for thorough multi-angle verification, verity_batch for up to 10 claims at once, and verity_agent for natural language queries. Each call costs between 0.10 and 0.75 USDC on Base. Maintains persistent memory across sessions if you pass a consistent caller_id, so it remembers what you've already checked. Useful when you need to validate information against current web sources or catch outdated claims in documentation and content.
