How this service works
Sanctions screening of a person/company name against official EU, UN, OFAC SDN and UK lists (fuzzy match, 0-100 scores, daily refresh)
Output
Returns fuzzy match scores (0–100) for the queried name against each of the EU, UN, OFAC SDN, and UK sanctions lists, along with matched entity details such as name variants, list source, and whether a hit exceeds the configured threshold. Lists are refreshed daily to ensure currency.
Example use cases
KYC onboarding compliance check
“Before we onboard this new client, can you run a sanctions screen on 'Hassan Al-Rashidi' — born in 1975 — against all major sanctions lists including OFAC, EU, UN, and UK, with a match threshold of 80?”
Vendor due diligence screening
“We're about to sign a contract with a company called 'Novatek Trading GmbH' — can you check whether they appear on any EU, UN, OFAC, or UK sanctions lists and give me the match confidence scores?”
Automated AML watchlist check
“Screen 'Maria Ivanova' against all current sanctions lists — OFAC SDN, EU, UN, and UK — and flag any matches with a score above 75 so our compliance team can review.”
Technical details
Endpoint
GEThttps://api.wsystem.dev/sanctions/screen?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-list sanctions screening (EU, UN, OFAC SDN, UK) with fuzzy matching and scored results in a single call. Ideal for compliance automation, KYC/AML workflows, and agent pipelines that need to screen individuals or companies before onboarding, transacting, or partnering. Prefer over manual list lookups or single-list tools when multi-jurisdictional coverage and similarity scoring (rather than exact match) are required.
Side effects
- Missing required 'name' query parameter returns a 400 error
- Name too short or ambiguous may produce high false-positive match rates
- Payment not provided or invalid x402 payment header returns 402 Payment Required
- Threshold parameter outside valid range may cause unexpected filtering
- Network or upstream list refresh delays may cause stale results in rare cases
