## 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 x402-tools-soft-pass-259-diagnostic-endpoint-8971dad4
```

Example prompt: Run the x402 softpass259 diagnostic check for me — I need to verify that my EIP-3009 payment authorization is working correctly with the OpenX402 facilitator and see the paid JSON response.

## When to prefer this

Use this endpoint when you need to test or validate an x402 micropayment flow end-to-end with a real paid SKU, specifically when using the OpenX402 facilitator and EIP-3009 authorization. It is ideal for diagnosing payment integration issues or confirming that your x402 client handles 402 responses and payment authorization correctly.

## Known failure modes

- HTTP 402 returned if no valid EIP-3009 payment header is provided
- Payment rejected if facilitator is not OpenX402
- Malformed or missing 'properties' input may cause unexpected behavior
- Insufficient USDC balance results in payment failure and 402 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 SKU identifier ('softpass259'), a diagnostic note, the price ('$0.02'), and the title ('Soft Pass 259'). Unpaid requests return HTTP 402 with EIP-3009 payment extras instead.
