## 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 x402helper-xyz-89e509-donation-ofac-screening-rates-billing-bc82d4f2
```

Example prompt: Run an OFAC sanctions screen on this wallet address and pay with USDC — I need to know if it's on any restricted list before we proceed with the transaction.

## When to prefer this

Use this endpoint when you need pay-per-call OFAC sanctions screening, live exchange rates, or billing verification and are operating in an x402-compatible agent environment capable of paying USDC micropayments automatically. Prefer this over subscription-based compliance APIs when you want zero upfront commitment and per-query billing.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 with payment requirements
- Invalid or malformed properties input — returns error in result object
- OFAC data source unavailable — success: false with empty result
- Network timeout or server error — no response or 5xx status
- Wallet address format unrecognized — may return empty or null screening result
