## 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-211-diagnostics-c056772a
```

Example prompt: Run the SKU Delta 211 x402 diagnostic and show me the paid JSON response — I want to confirm the OpenX402 facilitator payment flow is working correctly for a $0.02 USDC call.

## When to prefer this

Choose this endpoint when you need to test or validate the x402 HTTP micropayment protocol with a real paid SKU endpoint, specifically to confirm OpenX402 facilitator behavior, inspect HTTP 402 + EIP-3009 response extras, or verify the JSON shape of a successfully settled $0.02 USDC payment. It is a diagnostics/test endpoint, not a production data service.

## Known failure modes

- HTTP 402 returned with eip3009 extras when no valid x402 payment header is present
- Payment rejected by OpenX402 facilitator if token or signature is invalid
- Malformed properties input may result in unexpected response
- Facilitator unavailability may cause payment settlement failure

## 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 ('skudelta211'), a human-readable title ('Sku Delta 211'), the price ('$0.02'), and a diagnostic note. Unpaid requests return HTTP 402 with EIP-3009 payment extras instead.
