Sanctions and Watchlist ScreeningService

sanctions-watchlist-screen

Sanctions screening against the US OFAC SDN list, matching names and OFAC's official aliases with a fuzzy token-overlap score (0-100). POST JSON {"name": "..."} to /v1/ofac; the response is a JSON object with matches (name, matched_on, program, confidence), clear, clear_scope and checked_lists. EU, UN and UK lists are NOT screened; checked_lists marks each list checked or not_checked, so clear means clear of OFAC SDN only. Output is identical across suppliers holding the same OFAC list version (as_of).
