Check websites and domains against the SDN list to avoid interacting with bad actors, wherever they are.
Explore the OFAC APIGET /api/v1/screen/id/{id}
Look up passports, driver's licenses, tax identifiers and other government-issued IDs — partial IDs surface candidate matches ranked by similarity, so you get all the context to decide if escalation is needed.
Explore the OFAC APIGET /api/v1/screen/country/{country}
OFAC doesn't provide an explicit list of sanctioned countries, but there are a range of designations: comprehensive, targeted and military that CompliAPI has curated and made easily accessible.
