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 with a 'found' boolean, the entity details (name and entity number) if matched, a disclaimer noting this is directional/not a clearance, and the timestamp of the SDN list version used.
Example use cases
Pre-transaction sanctions entity check
“Before we process this wire, check OFAC SDN entity number 892 and tell me if it's a hit and what name is associated with it.”
Compliance audit entity verification
“I need to verify entity number 1042 against the OFAC SDN list for our compliance audit — pull the current record and tell me if it's found.”
Automated agent sanctions screening
“Screen OFAC entity number 306 for me — I need to know if it's on the SDN list and what the entity name is before I flag it for review.”

Endpoint
POSThttps://x402-ofac-api.vercel.app/api/v1/entity?utm_source=zero.xyzWhen to prefer
Use this endpoint when you already have a specific OFAC SDN entity number and need to retrieve the corresponding record directly — it is faster and more precise than fuzzy name screening. Prefer this over name-based screening when the entity number is known from a prior lookup or database. Best for agent workflows that need pay-per-call, audit-trail-friendly OFAC checks without a subscription.
Side effects
- Entity number not found — returns found: false with no entity details
- Invalid or malformed ent_num input — may return validation error
- Payment failure via x402 protocol — call not executed if USDC payment not confirmed
- OFAC list data temporarily unavailable — service may return error
- Rate limiting or infrastructure issues on Vercel hosting
