## 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-sku-delta-10n-diagnostics-19a9d9b6
```

Example prompt: Run the skudelta10n x402 diagnostic and show me the paid JSON response — I want to confirm the OpenX402 facilitator payment gate is working correctly for my $0.02 USDC SKU.

## When to prefer this

Use this endpoint when you need to test or demonstrate x402 HTTP payment gating behavior, specifically with the OpenX402 facilitator and EIP-3009 authorization. It is best suited for developers validating their x402 client integration, inspecting the 402 error payload shape, or confirming that a paid USDC micro-payment successfully unlocks a gated API response.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided, with EIP-3009 payment instruction extras
- Invalid or expired EIP-3009 authorization results in payment rejection
- Non-OpenX402 facilitators are not accepted, causing facilitation failure
- Malformed properties parameter may result in unexpected response shape

## 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 ('skudelta10n'), a diagnostic note clarifying this is a paid response shape, the price ($0.02), and the title ('Sku Delta 10n'). Unpaid requests instead return HTTP 402 with EIP-3009 payment extras describing how to pay.
