## 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-231-diagnostics-b9beb648
```

Example prompt: Run the x402 diagnostic for SKU delta 231 and show me the paid JSON response — I want to see what a successful $0.02 USDC payment returns from that endpoint.

## When to prefer this

Use this endpoint when you need a live, real-money x402 diagnostic to test or demonstrate the x402 micropayment protocol flow — specifically for verifying EIP-3009-based payment gating, OpenX402 facilitator behavior, and the shape of both paid success responses and unpaid 402 error responses. Not suitable for production data retrieval or non-x402 payment testing.

## Known failure modes

- HTTP 402 returned if payment is not included or insufficient — response includes EIP-3009 extras specifying payment requirements
- Invalid or missing properties parameter may result in unexpected response shape
- OpenX402 facilitator unavailability could block payment processing entirely
- Malformed payment header results in 402 rejection without settling

## 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 ('skudelta231'), a human-readable title ('Sku Delta 231'), the price ('$0.02'), and a diagnostic note. Unpaid requests receive HTTP 402 with EIP-3009 payment extras instead.
