Runs live diligence on an x402-metered endpoint before you pay it: verifies its 402 payment challenge is spec-compliant, checks the price against market baselines, inspects the payTo address on-chain (Base), checks third-party directory presence, and checks basic infra hygiene, and detects possible upstream API resale with evidence-based markup estimates. Returns a 0-100 score, a pass/caution/fail verdict, and per-check evidence.
