## 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 openclaw-x402-mint-pass-diagnostics-53b9d18d
```

Example prompt: Can you call the OpenClaw mintpass endpoint to test whether my x402 EIP-3009 USDC payment flow is working correctly and show me the paid response payload?

## When to prefer this

Choose this endpoint when you need to test or demonstrate the x402 HTTP payment protocol with EIP-3009 USDC micropayments, specifically using the OpenX402 facilitator. It is a diagnostic/reference endpoint ideal for verifying that your x402 client implementation correctly handles HTTP 402 responses, payment headers, and successful settlement before integrating with production paid APIs.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided, with EIP-3009 extras indicating required payment details
- Payment authorization rejected if USDC transfer signature is invalid or expired
- Facilitator unavailable if OpenX402 is down, causing payment settlement to fail
- Malformed properties parameter may result in an error response

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

A JSON object containing the mintpass SKU identifier, a human-readable title ('Mint Pass'), the price ($0.18), and a diagnostic note confirming the paid response shape. Unpaid requests return HTTP 402 with EIP-3009 payment requirement details instead.
