How this service works
SYNTHORA vessel-sanctions: screen any vessel (IMO or name) against the OFAC SDN sanctioned-vessels list (1,524 ships tracked) — the compliance check before touching tanker/shipping trades or chokepoint bets. List mode: full sanctioned-fleet snapshot. Source: OFAC SDN (US Treasury, free, no key). $0.03 USDC via x402 on Base.
Output
Returns a compliance verdict indicating whether the queried vessel (by IMO number or name) appears on the OFAC SDN sanctioned-vessels list, including relevant SDN entry details if matched. In list mode, returns a full snapshot of all 1,524 tracked sanctioned vessels from the US Treasury OFAC SDN database.
Example use cases
Pre-trade vessel compliance check
“We're about to settle a tanker freight deal — can you screen the vessel 'NORTH STAR VOYAGER' against the OFAC SDN list and tell me if it's sanctioned before we sign anything?”
Chokepoint shipping route due diligence
“I'm analyzing shipping exposure through the Strait of Hormuz — can you pull the full snapshot of all OFAC SDN sanctioned vessels so I can cross-reference our counterparty fleet?”
DeFi protocol collateral vessel risk check
“There's an on-chain shipping-backed loan using IMO 9234711 as collateral — check if that vessel is on the OFAC sanctioned-ships list before we approve the position.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/vessel-sanctionsWhen to prefer
Use this endpoint when you need a fast, low-cost OFAC SDN compliance check specifically for maritime vessels — either spot-checking a single vessel by IMO or name, or pulling a full sanctioned-fleet snapshot. Prefer this over general counterparty screening tools when the subject is specifically a ship or tanker. For combined OFAC + on-chain wallet + business risk checks, consider the broader counterparty business-risk endpoint on the same platform.
Side effects
- Vessel not found by name due to spelling variation or alias — try IMO number instead
- Ambiguous vessel name matching multiple entries — result may include multiple candidates
- OFAC SDN source data lag — list may not reflect same-day designations
- Invalid or malformed IMO number input returns an error
- Empty or missing input field returns a validation error
