How this service works
Before your agent onboards, pays, or contracts with a counterparty: screen the name against the U.S. Treasury OFAC sanctions lists (SDN + Consolidated non-SDN, synced every 6h) for $0.01. Benchmarked 114/114 sanctioned names found with zero false positives on a 152-case adversarial corpus of misspellings, word-order swaps, and transliterated aliases. Ranked candidates with confidence 0-100, program tags, and match evidence. Assistive screening signal, not a certified compliance determination.
Output
Returns a ranked list of candidate matches from the OFAC SDN and Consolidated non-SDN lists, each with a confidence score (0-100), the OFAC list entry details, applicable sanctions program tags, and matching evidence including alias hits and fuzzy/word-order-tolerant matches. An empty result indicates no hits as of the stated list version. The data is synced every 6 hours.
Example use cases
KYC screening for new customer onboarding
“Before we onboard this new supplier, can you quickly check if 'Gazprom Neft' shows up on any US sanctions lists and give me the confidence score on any matches?”
Vessel compliance check for shipping logistics
“We're about to route a shipment through a carrier using vessel 'MT Pegas' — can you verify whether this ship is under OFAC sanctions and show me any matches with their details?”
Transaction counterparty screening workflow
“I need to verify our trading partner 'Sberbank' against the OFAC SDN and consolidated lists before we execute this transaction — what confidence scores come back?”
Technical details
Endpoint
POSThttps://tollbooth-sanctions-screener.sjwilliams8.workers.dev/screen?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cost-effective, programmatic OFAC sanctions check with ranked confidence scoring and fuzzy/alias matching — especially useful for KYC/AML workflows, onboarding pipelines, or transaction screening where you need evidence of why a match was flagged. Prefer this over manual OFAC searches when screening at volume or when you need structured, auditable match evidence. Note: this is an assistive screening signal, not a certified compliance determination.
