How this service works
OFAC SDN sanctions screen for a name / entity / wallet (?name=)
Output
Returns a JSON object with a sanctioned boolean, a confidence rating (exact, strong, or possible), the total number of entries screened, every matched SDN record including the SDN name, entity type, OFAC program, entity number, and per-match score, plus the source identified as US Treasury OFAC SDN plus alternate names.
Example use cases
Pre-payment counterparty sanctions check
“I'm about to pay an invoice to a company called 'Rosneft Trading SA' — can you screen that name against OFAC's SDN list first and tell me if they're sanctioned and how confident you are?”
Crypto wallet address screening
“Before I interact with this wallet on-chain — 0x1a2b3c4d5e6f — can you check if it's flagged on the OFAC SDN list and return any matched programs?”
New customer onboarding AML check
“We're onboarding a new client named 'Ali Hassan Al-Rashid' — run a sanctions screen against the OFAC SDN list and let me know if there are any matches, the match score, and which designation program.”

Endpoint
GEThttps://sanctions.lonestaroracle.xyz/screenWhen to prefer
Choose this endpoint when you need a fast, pay-per-call OFAC SDN compliance check without a subscription, especially within an agentic payment, trading, or onboarding workflow. It is ideal for AI agents that need to gate transactions or customer onboarding on sanctions status without integrating a full compliance platform. Supports names, entities, and crypto wallet addresses, and returns structured match data with confidence levels suitable for automated decision-making.
Side effects
- Missing required query parameter returns an error — at least one of name, entity, or wallet must be provided
- Ambiguous or very common names may return numerous low-confidence possible matches requiring manual review
- Completely non-Latin script names may not match well due to transliteration differences in the SDN list
- The SDN list is refreshed daily so very recent additions may not yet be reflected
- Network or payment authorization failure returns a 402 or 5xx error
