Runs live pre-payment diligence on an x402-metered API endpoint, verifying spec compliance, pricing fairness, on-chain payTo address integrity, directory presence, infra hygiene, and resale markup detection, returning a 0–100 trust score with pass/caution/fail verdict.

Runs live due-diligence checks on an x402-metered API endpoint — validating 402 spec compliance, benchmarking price against market percentiles, inspecting the payTo address on-chain, and checking directory presence — then returns a 0-100 score, a pass/caution/fail verdict, and per-check evidence.
