How this service works

Screen a person/company/vessel name against OFAC (SDN + Consolidated), UN, EU, UK, Canada, Australia, France, Switzerland, US export-control (BIS/State), and US SAM procurement/benefit exclusions. Deterministic typo-tolerant fuzzy matching with versioned list snapshots.

Output

Returns a ranked list of potential sanctions matches, each with a fuzzy match score, the matched name, the sanctions list it appeared on (e.g. OFAC SDN, UN, EU, SAM), entity type, and metadata from the versioned list snapshot (e.g. DOB, nationality, aliases) to help determine if the hit is a true positive.

Example use cases

New customer KYC onboarding check

“Before we onboard this new customer, screen the name 'Chen Wei Trading Ltd' as an entity against OFAC, UN, EU and the other sanctions lists — return up to 5 matches with at least 0.8 confidence so I can review any hits.”

Vessel sanctions check before cargo deal

“We're about to sign a contract with a shipping company using the vessel 'Northern Star' — can you screen that vessel name against global sanctions lists to make sure it's not flagged, filtering to vessel type only?”

Government contractor debarment verification

“I need to check whether a supplier named 'Apex Defense Solutions' is excluded from US federal procurement — screen them as an entity against the SAM exclusions and any other US government lists, with a threshold of 0.75 and up to 10 results.”

When to prefer

Choose this endpoint when you need multi-jurisdictional sanctions screening in a single call — covering OFAC (SDN + Consolidated), UN, EU, UK, Canada, Australia, France, Switzerland, BIS/State export controls, and SAM procurement exclusions simultaneously. Its deterministic fuzzy matching with typo tolerance is ideal when input names may be transliterated, misspelled, or provided in variant forms. Prefer this over single-list checkers when compliance requires breadth across jurisdictions, or when you need to screen vessels and aircraft in addition to persons and entities.

Side effects

Name too short (< 2 characters) returns validation error
Threshold below 0.5 or above 1.0 is rejected
Limit exceeds 50 is rejected
No matches found returns empty results array (not an error)
Stale list snapshot if versioning lags behind real-world updates
False positives on common names requiring manual review
Network timeout on high-load queries
