How this service works
Sanctions-screen an EVM wallet address against the Chainalysis on-chain oracle (OFAC, EU, UN designated addresses). Returns a clear sanctioned / not-sanctioned result. For AML compliance, counterparty due diligence, and payment screening before sending funds.
Output
Returns the queried wallet address, a boolean 'sanctioned' field indicating whether it is designated, and an 'identifications' array listing any matching sanctions designations found via the Chainalysis oracle.
Example use cases
Example prompt
“Before I send funds, can you check if the wallet address 0x7FF9cFad3877F21d41Da833E2F775dB0569eef92 is sanctioned under OFAC, EU, or UN lists?”
Technical details
Endpoint
GEThttps://mcp.onchaindiligence.com/x402/screen/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a definitive, oracle-backed sanctions check on a specific EVM wallet address before executing a payment or onboarding a counterparty. It is backed by the Chainalysis on-chain oracle, which covers OFAC, EU, and UN designation lists, making it more authoritative than purely off-chain list checks. Prefer it for AML compliance workflows, payment pre-screening, and counterparty due diligence in DeFi or crypto payment contexts.
Side effects
- Invalid or malformed EVM address returns an error response
- Address not found on-chain oracle may return not-sanctioned with empty identifications
- Network or oracle unavailability may result in a timeout or 5xx error
- Payment failure (insufficient USDC) results in a 402 Payment Required response before the check is performed
