## 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-denyfresh-diagnostics-endpoint-5dd89cbe
```

Example prompt: Run the x402 DenyFresh diagnostic against the OpenX402 facilitator and show me the paid JSON response — I want to confirm my $0.02 USDC payment flow and EIP-3009 signing are working correctly.

## When to prefer this

Choose this endpoint when you need a real, live x402-gated API to test your HTTP 402 payment handling, EIP-3009 signing logic, or OpenX402 facilitator integration at minimal cost ($0.02 USDC). It is purpose-built for x402 protocol diagnostics rather than delivering production business data.

## Known failure modes

- HTTP 402 returned if payment header is missing or invalid — includes EIP-3009 extras for payment instructions
- Payment facilitated only through OpenX402; other facilitators will be rejected
- Invalid or malformed properties parameter may result in error response
- Network timeout or endpoint unavailability if openclawproductions.com is down
- Insufficient USDC balance or incorrect signing results in payment rejection

## How this service works

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

## Output

On successful paid request: a JSON object with fields 'sku' (denyfresh), 'note' (diagnostic description), 'price' ($0.02), and 'title' (Deny Fresh). On unpaid request: HTTP 402 with EIP-3009 payment metadata specifying the required USDC payment and facilitator details.
