Search vs Screen

• Search returns a broader, less restrictive result set — best for research and enhanced due diligence. Does not consider dissimilarity.
• Screen uses fuzzy matching with both similarity and dissimilarity analysis — best for automated compliance screening (onboarding, transactions). Reduces false positives.

Both accept up to 1000 cases per request.

Workflows

Quick sanctions check: Search a name against SDN + EU + UN. Review matches above score 85. Look up full entity details by ID for any hits.

KYC onboarding screen: Screen a person with name, DOB, citizenship, and nationality against all sources. Use min_score of 80-90. Flag any matches for manual review.

Batch compliance: Screen up to 1000 names in a single request. Filter by entity type to reduce noise (e.g., exclude vessels when screening individuals).

Entity research: Look up a known sanctioned entity by ID to get full details including aliases, addresses, programs, and identification documents.

Gotchas

• Source selection matters: Default is SDN only. For full coverage, pass all relevant source codes explicitly.
• Score threshold: Default min_score is 80. Lower scores (60-79) increase recall but also false positives. For production compliance, use 80-95.
• Subscription required: All endpoints require an active ofac-api.com subscription; a free 30-day trial is available.
