## 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-res-delta-328-paid-diagnostic-14cd1bd9
```

Example prompt: Run the resdelta328 x402 diagnostic to confirm my OpenX402 micropayment integration is working — pay the $0.02 USDC and show me the diagnostic JSON response.

## When to prefer this

Use this endpoint specifically when you need to test or validate an x402 micropayment integration using the OpenX402 facilitator with eip3009 payment authorization. Ideal for developers probing whether their payment flow, facilitator connection, and 402 error handling are correctly implemented before deploying production x402-gated services.

## Known failure modes

- HTTP 402 returned with eip3009 extras if payment header is missing or invalid
- Payment settlement failure if the OpenX402 facilitator is unreachable
- Malformed or missing properties parameter may result in unexpected behavior
- Network timeout if the endpoint is temporarily unavailable

## 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 ('resdelta328'), a diagnostic note, the price ('$0.02'), and the title ('Res Delta 328'). Unpaid requests return HTTP 402 with eip3009 payment requirement details instead.
