check_endpointRuns 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
compare_priceCompares an x402 endpoint's price (or a given price/category pair) against market percentiles from our daily radar snapshot of the x402 ecosystem.
reseller_checkFree possible-reseller preview. Matches an endpoint's live unpaid 402 description/schema, or a supplied description and price, against a dated catalog of well-known upstream APIs and reports confidence, matched signals, and documented markup math without asserting resale as fact.
