## 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: Can you run a sanctions check on wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE on Base and tell me if it's flagged by OFAC?

## When to prefer this

Choose this endpoint when you need a fast, lightweight OFAC/sanctions compliance check on a specific wallet or contract address on Base or other supported EVM chains. It is ideal for pre-transaction compliance gating, counterparty screening in DeFi workflows, or onboarding checks where you need a binary sanctioned/clear verdict plus basic on-chain metadata like transaction count. Prefer this over full blockchain explorers when you need a structured, machine-readable compliance summary rather than raw chain data.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain identifier may cause a lookup failure
- Address not found on the specified chain may return incomplete data
- Network timeout or upstream provider unavailability
- Rate limiting or payment failure via x402 micropayment protocol

## How this service works

One-call counterparty check: wallet activity profile (EOA vs contract, balances, tx count, risk flags) plus OFAC SDN sanctions screening, resolved into a single clear/blocked verdict. Reports 'unscreened' rather than 'clear' if the sanctions list could not be consulted.

## Output

Returns a JSON object with: verdict (e.g. 'clear'), tx_count (total on-chain transactions), sanctioned (boolean), is_contract (boolean), sanctions_list (e.g. 'OFAC SDN'), and sanctions_screened (boolean confirming the check was performed).
