## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Before I send this payment, can you run an OFAC sanctions check on the wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE to make sure it's not on any US sanctions list?

## When to prefer this

Use this endpoint when you need a fast, pre-transaction OFAC sanctions check on a specific EVM wallet address and want a simple pass/fail compliance signal without building your own OFAC list integration. Ideal for agents automating on-chain payments on Base or other EVM chains that must satisfy US regulatory compliance requirements.

## Known failure modes

- Invalid or malformed 0x address returns a validation error
- Address not in EVM format may be rejected
- Service unavailable on Railway deployment returns 5xx
- OFAC list data may have a refresh lag, missing very recently added addresses
- Payment failure (insufficient USDC) blocks the call

## How this service works

OFAC sanctions screening: is this address on the US OFAC sanctioned-address list? Send { address }. Every agent moving money legally needs this pre-transaction check.

## Output

Returns whether the given EVM address is present on the OFAC sanctioned-address list — a match/no-match status indicating whether the address is legally restricted from receiving funds under US law.
