How this service works
Meridian — DeFi risk cards for agents. Aave v3, Lido, vaults, deep passport, OFAC SDN screen, parameter-drift, and transaction simulation via x402 on Base.
Output
A JSON object containing: the screened address, the chain hint used, a boolean 'match' field indicating SDN presence, an array of matching SDN entries (empty if no match), the OFAC list version and last-updated timestamp, freshness in hours, data sources, a no-match disclaimer note, and any warnings. All data is informational and not a substitute for a compliance program.
Example use cases
Pre-trade counterparty sanctions check
“Before we execute this token swap with 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, can you screen that address against the OFAC SDN list on the ETH chain and confirm it's not sanctioned?”
DeFi protocol onboarding compliance gate
“We're onboarding a new user with wallet 0x71C7656EC7ab88b098defB751B7401B5f6d8976F — please run an OFAC sanctions screen on it before we allow them to deposit into our vault.”
Post-transaction risk audit
“Flag any of these three addresses — 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE, 0x1111567890abcdef1234567890abcdef12345678, 0xABCDEF0123456789ABCDEF0123456789ABCDEF01 — if they appear on the OFAC SDN list, and tell me when the list was last updated.”

Endpoint
GEThttps://workers.miodiollc.com/v1/sanctions/0x0000000000000000000000000000000000000001?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap ($0.005 USDC), exact-match sanctions screen of a single EVM wallet address against the public OFAC SDN Digital Currency Address list. Prefer it over the full Meridian Deep Passport or Bundle when you only need sanctions data without Aave v3, Lido, or vault risk context. Ideal for pre-trade compliance gates, onboarding checks, or any workflow where OFAC clearance is a required condition before proceeding.
Side effects
- Invalid or malformed address format returns an error response
- Unknown or unsupported chain hint may default to cross-chain exact match or return a warning
- OFAC list temporarily unavailable causes freshness_hours to be null or elevated
- Address with mixed-case checksum issues may fail exact match — normalize address before calling
- Rate limiting or payment failure (x402) if USDC balance is insufficient
