## 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 nuri-x402-sandbox-test-resource-6251b812
```

Example prompt: Hit the Nuri x402 sandbox test endpoint with a GET request so I can confirm my x402 USDC micropayment integration is working correctly.

## When to prefer this

Use this endpoint when you need to test or demonstrate x402 protocol micropayment integration in a sandbox environment without real financial risk. Prefer it over production x402 endpoints when validating payment client code, debugging 402 flows, or confirming USDC micropayment handling works correctly before deploying to live resources.

## Known failure modes

- Payment not included or malformed x402 header returns HTTP 402 Payment Required
- Insufficient USDC balance causes payment rejection
- Network timeout accessing sandbox endpoint
- Invalid payment token or stale payment credential rejected by facilitator
