## 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-donation-micropayment-endpoint-44f5b862
```

Example prompt: Run an OFAC sanctions screening check and return the result — I'll pay the $0.013 USDC fee via x402.

## When to prefer this

Use this endpoint when you need pay-per-call OFAC screening, exchange rate lookup, or billing verification and are operating in an x402-compatible agent environment capable of making USDC micropayments on Base or compatible chains. Avoid if you need free or subscription-based compliance APIs, or if your agent stack does not support x402 payment headers.

## Known failure modes

- Payment not included or invalid — returns HTTP 402 requiring payment
- OFAC screening data unavailable — result object may be empty or null
- Invalid or missing 'properties' parameter — may return generic or empty result
- Domain not reachable — connection timeout or DNS failure
- Repeated identical endpoint names across siblings suggest possible auto-generated stub — actual data fidelity uncertain
