How this service works
Are any of these crypto addresses on OFAC’s SDN sanctions list? Up to 100 addresses screened in one call, checked by Distill against OFAC’s own SDN file. Updated daily. $0.05 per call (x402, USDC on Base); 3 free calls a day.
Output
Returns a result for each submitted crypto address indicating whether it appears on OFAC's SDN sanctions list, based on a daily-updated copy of the official OFAC SDN file maintained by Distill. Up to 100 addresses are screened per call.
Example use cases
Pre-payment sanctions compliance check
“Before we send out these 50 USDC payouts, can you screen all the recipient wallet addresses against the OFAC SDN list and flag any that show up as sanctioned?”
Exchange onboarding KYC screening
“We just got a batch of 80 new user wallet addresses from our onboarding flow — can you run them all through the OFAC sanctions database and tell me which ones, if any, are on the SDN list?”
DeFi protocol counterparty vetting
“Can you check whether any of these 15 wallet addresses that interacted with our smart contract yesterday are on OFAC's sanctions list? I need to know before we allow further transactions.”
Technical details
Endpoint
POSThttps://data.spencermcw.com/v1/sanctions/address/batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to screen multiple crypto wallet addresses (up to 100) against the OFAC SDN list in a single API call for compliance, AML, or pre-transaction vetting workflows. It's ideal for batch use cases like exchange onboarding, DeFi protocol risk checks, or payment processor compliance pipelines. Prefer it over single-address lookup when processing lists of wallets, and over building your own SDN parser when you need a maintained, daily-updated feed via a simple POST call.
Side effects
- Empty or missing addresses array returns validation error
- More than 100 addresses in a single call exceeds the batch limit
- Malformed or non-string address entries may cause parsing errors
- Stale data risk: list is updated daily so very recent OFAC additions may not be reflected immediately
- Payment failure via x402 if USDC balance on Base is insufficient
- Rate limiting after 3 free daily calls without payment
