## 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-mining-capitulation-endpoint-66e4545a
```

Example prompt: Can you check the OFAC sanctions status or current rates using the x402helper mining endpoint — I'll pay the $0.009 USDC fee per call.

## When to prefer this

Only consider this endpoint if you specifically need x402-protocol micropayment-gated access to OFAC screening, exchange rates, or billing verification at $0.009 USDC per call and have confirmed the endpoint delivers the claimed data. The low crawl quality score, suspicious URL path (mining/capitulation), and repetitive sibling endpoints are significant red flags — prefer established, well-documented compliance or rate APIs if available.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or missing properties parameter — may return empty or error result
- Endpoint path does not correspond to documented functionality — result object may be empty
- OFAC or rate data unavailable — success may be false with empty result
- Network timeout or server unavailability
