## 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 ofac-sanctions-address-checker-21c4e840
```

Example prompt: Before I send any funds, can you check whether the wallet address 0x252a8bd2319d8a555b872990601221b3a2053bce is on the OFAC sanctions list?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call OFAC sanctions screen for crypto wallet addresses with no API key or account setup required. It is ideal for AI agents that need occasional compliance checks without committing to a subscription service. Prefer this over full KYC/AML platforms when you only need address-level sanctions screening rather than identity verification or full transaction monitoring.

## Known failure modes

- Missing or invalid address query param returns 400 error
- More than 20 comma-separated addresses in a single request may be rejected
- Payment failure via x402 protocol prevents request from completing
- Malformed address strings may return no match rather than an error
- Stale sanctions list if list build timestamp is old (builtAt field should be checked)

## How this service works

Small pay-per-call utility APIs for AI agents. Pay per request in USDC on Base via x402 (v2, exact scheme). No accounts, no API keys.

## Output

Returns a JSON object with: the sanctions list build timestamp and total address count, per-address results listing any matching sanctioned entity names, asset types (e.g. ETH, BTC), and program codes (e.g. CYBER2), plus a boolean anySanctioned field indicating whether any of the queried addresses are sanctioned.
