OFAC sanctioned crypto-address screening API

Screen a crypto address against the official US Treasury OFAC SDN digital-currency-address list, returning not just a sanctioned boolean but WHO it belongs to (entity name + SDN entry number), WHICH sanctions program(s) it falls under, and the chain — across every chain OFAC tracks (BTC, ETH, TRX, XMR, USDT, etc.). The authoritative SDN CSV is snapshotted daily and served as instant lookups. Answers 'is this wallet sanctioned by OFAC', 'who does this sanctioned address belong to', 'what program is this address under', 'screen this crypto address for compliance'.
