## 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-hdr-alias-diagnostic-edf16b19
```

Example prompt: Run the x402 hdralias diagnostic using a GET request so I can see what the paid JSON payload looks like after the micropayment goes through — I want to verify the SKU name, price, and title in the response.

## When to prefer this

Choose this endpoint when you need to test, validate, or demonstrate x402 HTTP 402 payment-gating behavior, particularly with the EIP-3009 payment standard and the OpenX402 facilitator. It is the right choice for developers building or debugging x402-compatible payment flows, inspecting micropayment challenge responses, or verifying that a paid API correctly returns its payload after successful USDC settlement.

## Known failure modes

- HTTP 402 returned when no valid x402 payment token is provided — includes EIP-3009 payment challenge extras in response body
- Invalid HTTP method (e.g. POST) returns 405 Method Not Allowed — only GET, HEAD, DELETE supported
- Malformed or expired EIP-3009 payment token results in payment rejection
- OpenX402 facilitator unavailable causes payment settlement failure
- Invalid or unreachable URL in queryParams.url may cause request errors

## 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' (hdralias), 'note' (diagnostic description), 'price' ($0.03), and 'title' (Header Alias). If the request is not accompanied by valid x402 payment, returns HTTP 402 with EIP-3009 payment challenge extras instead.
