How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
Returns a JSON object with a boolean 'sanctioned' field indicating whether the address is flagged, and a 'lists' array naming the specific sanctions lists (e.g. 'OFAC SDN (ETH)') on which it appears. If not sanctioned, lists is empty and sanctioned is false.
Example use cases
Pre-transfer compliance check
“Before I send USDC to 0xAbCd1234...5678, can you verify that wallet isn't on any OFAC or government sanctions list?”
DeFi protocol onboarding screen
“We're onboarding a new user whose wallet is 0xDeAdBeEf...9999 — can you run a sanctions check on that address to make sure it's not flagged by OFAC or other regulators?”
Automated AML monitoring for transactions
“Flag any incoming transaction from a sanctioned wallet — can you check if 1A2B3C4D5E6F... appears on any sanctions lists right now?”
Technical details
Endpoint
GEThttps://skinwinking.com/api/v1/data/sanctions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap ($0.002 per call) pay-per-use sanctions screening for any blockchain wallet address without a subscription. Ideal for agents automating compliance checks before executing on-chain transfers, onboarding users, or flagging high-risk counterparties. Prefer over enterprise AML platforms when low-volume, programmatic, per-call billing is needed and OFAC SDN coverage is sufficient.
Side effects
- Missing 'address' query parameter returns a validation error
- Malformed or invalid wallet address format may return an error or empty result
- Address not found on any list returns sanctioned: false with empty lists array
- Payment failure over x402 results in 402 response blocking the query
- Chain-specific addresses may not be recognized if the format is unsupported
