How this service works
Batch sanctions screening of up to 50 names against official EU, UN, OFAC SDN and UK lists
Output
Returns a batch of screening results for each submitted name, including whether a match was found, which sanctions list(s) matched, the matched entity name, similarity score, and any available details about the sanctioned entity such as nationality or designation reason.
Example use cases
Onboarding batch KYB sanctions check
“I need to onboard 10 new suppliers and want to screen all their company names against EU, OFAC, UN, and UK sanctions lists before we sign contracts — can you run them all through at once with a threshold of 0.8?”
AML compliance sweep for customer list
“We have a list of 50 customer names from our latest sign-ups — can you check them all against the official sanctions watchlists and flag anyone with a match score above 0.85?”
Investor due diligence screening
“Before we close this funding round, can you screen these three investor names — Viktor Orlov, Sun Capital Partners, and Meridian Holdings — against OFAC SDN, EU, UN, and UK sanctions lists with a 0.9 threshold?”
Technical details
Endpoint
POSThttps://api.wsystem.dev/sanctions/screen/batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to screen multiple entities in a single API call rather than one at a time, especially for onboarding workflows, compliance sweeps, or due diligence pipelines where throughput matters. Prefer this over the single-name endpoint when processing lists of 2 or more names to minimize API calls and cost. Best for AML, KYB, and KYC workflows requiring cross-list coverage (EU, UN, OFAC SDN, UK) with fuzzy matching to catch name variations and transliterations.
Side effects
- Empty or missing names array returns a validation error
- Threshold value outside 0–1 range may be rejected or default applied
- Very common names may return high false-positive rates at low thresholds
- Payment failure (x402) blocks the call if USDC funds are insufficient
- Rate limiting if too many names are submitted in a single batch
- Sanctions list data may have a small lag behind official source updates
