## 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-stubshare34-diagnostic-endpoint-25903bc4
```

Example prompt: Run a paid x402 diagnostic on the stubshare34 SKU endpoint to confirm the payment flow works — I want to see the stub JSON response after the $0.02 USDC charge settles through OpenX402.

## When to prefer this

Use this endpoint when you need to test or validate an x402 HTTP payment-gating integration using OpenX402 as the facilitator. It is ideal for verifying that your agent or client correctly handles HTTP 402 responses with eip3009 extras, completes a USDC micropayment, and successfully retrieves the gated resource. Prefer this over real production endpoints when you want a safe, low-cost ($0.02 USDC) stub to prove out payment flows without side effects on live data.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided — expected diagnostic behavior, includes eip3009 extras
- Invalid or expired EIP-3009 authorization results in payment rejection
- OpenX402 facilitator unavailable causes settlement failure
- Malformed properties input may return 400 or unexpected stub response
- Network timeout if OpenX402 payment facilitation is slow to settle

## 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: sku ('stubshare34'), note (example paid JSON shape disclaimer), price ('$0.02'), and title ('Stub Share 34'). Without payment, returns HTTP 402 with EIP-3009 payment extras in the response headers/body for x402 protocol diagnostics.
