POST /v1/address-screen
unprobed
Pay-to / counterparty address screen for Base: exact match against OFAC SDN published digital currency addresses (daily refresh, list date included), contract vs EOA, Blockscout verification, first-seen age and tx count, lookalike (address-poisoning) check vs an optional compare_to, labels, and a block/caution/ok verdict. $0.005 USDC. Screening aid only, not a compliance clearance or legal advice.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
