How this service works
x402 v2 pay-per-call. Unpaid requests receive HTTP 402 with payment requirements.
Output
Returns a compliance verdict indicating whether the given EVM address appears on the OFAC Specially Designated Nationals (SDN) list, including match status and any relevant sanctions details about the address.
Example use cases
Pre-transaction sanctions compliance check
“Before I transfer USDC to 0xAbCd1234567890abcdef1234567890ABCDEF1234, can you verify it isn't on the OFAC SDN list?”
DeFi protocol counterparty screening
“We need to check whether the wallet 0xDeadBeef00000000000000000000000000000001 is flagged by OFAC — our protocol needs to block sanctioned addresses from interacting.”
Crypto exchange onboarding AML check
“Run an OFAC sanctions check on the EVM address 0x9999aaaa1111bbbb2222cccc3333dddd4444eeee so we can decide whether to approve this new user's withdrawal request.”

Endpoint
GEThttps://chainverdict.xyz/v1/screen/address/%7Baddr%7DWhen to prefer
Use ChainVerdict when you need a pay-per-call, low-cost OFAC SDN screening specifically for EVM blockchain addresses, especially in agent workflows that require micropayment-gated compliance checks via the x402 protocol. Prefer this over bulk compliance services when you only need on-demand, single-address lookups at $0.001 per call with no subscription overhead.
Side effects
- HTTP 402 returned if payment is not provided via x402 protocol before calling
- Invalid or malformed EVM address may result in a 400 error or no match
- Address not found in SDN list returns a clean/not-sanctioned result (true negative)
- Network timeouts or upstream SDN list unavailability may cause 503 errors
- OFAC list may have propagation delay meaning very recently added addresses could be missed
