How this service works

Screen any person, company, or entity against OpenSanctions -- 1.3M+ entries from OFAC SDN, EU Sanctions, UN List, and 330+ sources. Returns sanctioned: true/false, entity type, risk topics (sanction, debarment, role.pep), and source datasets. Optional: country (ISO-2), address, birthDate narrow false positives. For AML/KYC pre-screening and off-ramp compliance. Pay with USDC on Base, Polygon, or Arbitrum.

Output

Returns a JSON object with: sanctioned (true/false boolean), the submitted name, matchCount (number of distinct matched entities), and a matches array where each entry contains entityId, caption, entityType, risk topics (e.g. sanction, debarment, role.pep), matchedOn fields, and source datasets. Empty matches array means clean result.

Example use cases

Verify counterparty before wire transfer

“I'm about to send a large wire to a company called Acme Trading LLC based in Dubai. Can you quickly screen them against OFAC and other sanctions lists to make sure we're not violating any compliance rules?”

KYC screening for new crypto customer

“We just got a signup from someone claiming to be from Turkey. Run a full sanctions check on 'Mehmet Yilmaz', born 1985, against all the major lists — I want to make sure they're not a PEP or on any watchlists before we onboard them.”

Debarment check on business partner

“Before we sign this distribution agreement with a company in Singapore, can you check if their CEO 'Raj Kumar' shows up as debarred or sanctioned anywhere? I need to verify their clean status for our records.”

Technical details

Endpoint

GEThttps://scan.madhousewallet.com/api/public/sanctions-check?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a comprehensive sanctions and PEP check against 330+ global sources including OFAC SDN, EU Sanctions, and UN List in a single call. Ideal for AML/KYC pre-screening, crypto off-ramp compliance, or due diligence workflows. Prefer over individual list checks when you need broad multi-jurisdictional coverage. Use birthDate and country parameters to reduce false positives for common names.

Side effects

Missing required 'name' parameter returns 400 error
Common names without country/birthDate may return multiple matches causing ambiguity
Payment failure if USDC balance insufficient on Base/Polygon/Arbitrum
False positives for common names when no disambiguation parameters provided
Entity not found in database returns sanctioned: false with empty matches array
