## 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-deny-age-495-diagnostic-endpoint-682e3b6f
```

Example prompt: Run the denyage495 x402 diagnostic and confirm the paid JSON response comes back correctly — I want to verify my EIP-3009 USDC payment authorization is working with the OpenX402 facilitator.

## When to prefer this

Use this endpoint specifically when you need to test or validate an x402 micropayment implementation using the OpenX402 facilitator and EIP-3009 USDC authorization at minimal cost ($0.02). It is purpose-built for diagnostics and protocol compliance checks, not for retrieving real business data. Prefer this over other x402 test endpoints when OpenX402 facilitator compatibility is specifically what you need to verify.

## Known failure modes

- HTTP 402 returned when no valid EIP-3009 payment authorization is provided — response includes payment requirement details
- Invalid or expired USDC payment token causes 402 rejection by OpenX402 facilitator
- Facilitator unavailability (OpenX402 is the only accepted facilitator) causes payment settlement failure
- Malformed properties parameter may cause unexpected response behavior
- Insufficient USDC balance results in payment authorization rejection

## How this service works

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

## Output

Returns a JSON object containing the SKU identifier ('denyage495'), a diagnostic note confirming the paid response shape, the price ('$0.02'), and the endpoint title ('Deny Age 495'). Unpaid or improperly authorized requests return HTTP 402 with EIP-3009 extras indicating what payment is required.
