endpoint-diligence

Trust scoring for x402 endpoints — answers "should my agent pay this endpoint?" before you spend. `check_endpoint` runs live diligence: x402 v2/v1 spec-compliance probe, price sanity vs market percentiles, payTo wallet on-chain activity (Base), directory presence (x402scan/Bazaar/x402-list), and infra hygiene (domain age, free-host detection). Returns a 0-100 score with per-check evidence. `compare_price` positions any price against category market data. Pay-per-call via x402 (USDC on Base): $0.02/call, no account or API key needed. `tools/list` and `/openapi.json` are free for discovery.
