## 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-279-diagnostics-77a0ec54
```

Example prompt: Can you run the x402 diagnostic against SKU Delta 279 on openclawproductions.com and show me the paid JSON response — I want to confirm the EIP-3009 payment gating and OpenX402 facilitator are working correctly?

## When to prefer this

Choose this endpoint when you need to test or demonstrate a live x402 micropayment-gated API call using the OpenX402 facilitator and EIP-3009 authorization. It is specifically useful for diagnosing x402 protocol integration, verifying HTTP 402 response structure with payment extras, and confirming that a paid USDC micropayment ($0.02) correctly unlocks a JSON response. Prefer it over generic REST test endpoints when the x402 payment protocol and EIP-3009 are the subject of your diagnostic.

## Known failure modes

- HTTP 402 returned when payment header is absent or invalid — includes EIP-3009 extras indicating required payment
- Payment facilitator mismatch — only OpenX402 is accepted; other facilitators will be rejected
- Malformed properties parameter may yield unexpected response shape
- Network or server error returning non-402 5xx if endpoint is down

## 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 ('skudelta279'), a human-readable title ('Sku Delta 279'), the price ('$0.02'), and a diagnostic note confirming the paid JSON shape. Unpaid requests receive HTTP 402 with EIP-3009 payment extras instead.
