## 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`):

```sh
zero fetch --capability bot-bazaar-ofac-sdn-evm-address-sanctions-screener-e8266b3b
```

Example prompt: Can you check whether the wallet address 0x4e9ce36e442e55ecd9025b9a6e0d88485d628a67 is on the OFAC SDN sanctions list before I send any funds to it?

## When to prefer this

Choose this endpoint when you need a fast, inexpensive ($0.01 USDC) point-in-time OFAC SDN sanctions check specifically for EVM/Base blockchain addresses. It is purpose-built for crypto compliance workflows where you need to verify a single 0x address before executing a transaction or onboarding a user. Prefer this over general AML APIs when the address is on the Base/EVM network and you need the OFAC SDN digital-currency list specifically, with freshness metadata included in the response.

## Known failure modes

- Invalid address format (not 0x + 40 hex) returns a validation error
- OFAC SDN list temporarily unavailable causing stale or failed refresh
- Network timeout from the upstream OFAC data source
- Payment not received or insufficient USDC balance causes 402 rejection
- Address provided as checksummed EIP-55 may need normalization

## How this service works

Standalone OFAC SDN digital-currency sanctions address screen for an EVM address on Base (0x + 40 hex). Screens against the daily OFAC SDN ETH/EVM address list and returns match status, matched addresses, list size, and last-refreshed timestamp.

## Output

Returns a JSON object indicating whether the queried EVM address matches any entry on the OFAC SDN digital-currency list, the specific matched addresses if any, the total number of addresses in the current SDN list, and the timestamp of when the list was last refreshed.
