## 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-hl-spot-diagnostic-endpoint-2dbeefbe
```

Example prompt: Can you call the x402 hlspot diagnostic endpoint and show me what the paid JSON response looks like — I want to see the SKU, price, and title fields to verify my OpenX402 payment flow is working correctly.

## When to prefer this

Choose this endpoint when you need to test, diagnose, or demonstrate x402 HTTP payment-gating behavior using the OpenX402 facilitator, particularly to validate EIP-3009 payment flows or inspect what a paid vs. unpaid x402 response looks like for the hlspot SKU.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is present — includes EIP-3009 payment instructions
- Facilitator not OpenX402 — requests from other facilitators may be rejected
- Invalid or malformed properties parameter — may result in error or unexpected response
- Network timeout or service unavailability on openclawproductions.com

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

On successful payment: a JSON object containing 'sku' (hlspot), 'note' (diagnostic description), 'price' ($0.03), and 'title' (HL Spot). On unpaid request: HTTP 402 response with EIP-3009 payment extras indicating the required payment details.
