## 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-denyageflip-diagnostics-935f219d
```

Example prompt: Run the denyageflip diagnostic on OpenX402 so I can verify my x402 USDC payment flow is working end-to-end.

## When to prefer this

Choose this endpoint when you need a real, live x402-gated endpoint to test HTTP 402 payment flows, EIP-3009 token authorization, or OpenX402 facilitator integration. It is purpose-built for diagnostics and protocol validation, not for production data retrieval.

## Known failure modes

- HTTP 402 returned if payment header is missing or invalid — includes EIP-3009 extras useful for debugging
- Non-OpenX402 facilitators are rejected; only OpenX402 is supported as facilitator
- Malformed properties input may return an error or be silently ignored
- USDC payment authorization failure leads to 402 with no diagnostic payload

## 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 diagnostic SKU name ('denyageflip'), a human-readable note clarifying this is an example paid shape, the price ('$0.02'), and the title ('Deny Age Flip'). Without payment, returns HTTP 402 with EIP-3009 extras for debugging.
