How this service works
Pay-per-call directional OFAC SDN screen for AI agents (USDC on Base + Solana via x402). Potential matches only — not clearance.
Output
Returns a JSON object containing: a list of hits (each with a match score, entity name, and match type such as primary or alias), the original query, total hit count, the date the SDN list was last updated, and a disclaimer stating these are directional potential matches only — not legal clearance.
Example use cases
Vendor onboarding sanctions check
“Before we onboard this new supplier, can you screen the name 'Rosneft Trading SA' against the OFAC SDN list — use a threshold of 0.65 and give me up to 20 results?”
Customer KYC screening
“I need to run a quick OFAC SDN check on a new customer called 'Ali Hassan Al-Moayed' — use default threshold and return up to 25 potential matches so I can review them.”
Investment counterparty due diligence
“We're about to wire funds and I want to screen our counterparty 'Iranian Development Bank' against the OFAC SDN sanctions list before we proceed — set the threshold to 0.7 and cap results at 10.”
Technical details
Endpoint
POSThttps://x402-ofac-api.vercel.app/api/v1/screen?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call OFAC SDN fuzzy screen without committing to a subscription-based compliance service. It is ideal for AI agents performing ad hoc sanctions checks on individual names during onboarding, due diligence, or transaction workflows. It is not a substitute for certified compliance clearance — use it as a directional signal to flag potential matches for human review.
Side effects
- Name query returns zero hits even for known sanctioned entities if threshold is set too high — lower the threshold to improve recall
- Fuzzy matching may produce false positives for common names — review scores carefully before acting
- SDN list date ('list_as_of') may lag real-time OFAC updates — check currency before relying on results for high-stakes decisions
- Malformed or missing 'query' field returns a validation error
- Exceeding the max limit of 50 hits is silently capped or returns an error depending on implementation
- Payment failure via x402 prevents the call from completing
