## 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-sku-delta-201-diagnostics-endpoint-d250586b
```

Example prompt: Run a quick x402 payment diagnostic against the skudelta201 SKU — I want to confirm my client can settle a $0.02 USDC payment through OpenX402 and get back the paid JSON response.

## When to prefer this

Choose this endpoint when you need a live, low-cost ($0.02 USDC) x402 micropayment integration test against a real paid SKU gated by the OpenX402 facilitator. It is particularly useful for validating EIP-3009 payment flows, inspecting HTTP 402 response shapes with payment metadata, or confirming that your x402-capable agent or client can correctly settle and retrieve a paid API response. Prefer it over mock or sandbox endpoints when you need real on-chain payment confirmation behavior.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is present, with EIP-3009 extras describing required payment
- Payment processed by a facilitator other than OpenX402 may be rejected or not recognized
- Malformed EIP-3009 authorization results in payment rejection and 402 response
- Network or chain congestion may delay payment settlement confirmation
- Invalid or missing 'properties' query parameter may yield an unexpected or empty 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 ('skudelta201'), a human-readable title ('Sku Delta 201'), the price ('$0.02'), and a diagnostic note clarifying this is an example paid JSON shape. Unpaid requests receive HTTP 402 with EIP-3009 payment metadata instead.
