Checks one crypto address against the OFAC SDN list published by the US Treasury, across 16 currencies including Ethereum, Bitcoin, Tron and USDT. A hit returns the actual list entry - sanctioned entity, its type and its sanctions programmes - not a risk score. Exact matching only, never fuzzy. Every answer carries the publication date of the list snapshot. No API key, no account.
