## 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-invent-gap-3-diagnostic-e56f7aee
```

Example prompt: Run the x402 diagnostics check for the 'inventgap3' SKU using OpenX402 as the facilitator and confirm I get a valid paid JSON response back after the $0.02 USDC payment goes through.

## When to prefer this

Choose this endpoint when you need to test or validate an x402 micropayment integration end-to-end with a real $0.02 USDC charge via OpenX402. It is specifically designed as a diagnostic tool for developers building on the x402 protocol who need a live paid SKU to probe against, confirm EIP-3009 payment header behavior, or verify facilitator settlement.

## Known failure modes

- HTTP 402 returned if payment token is missing or invalid — includes eip3009 extras describing payment requirements
- Payment facilitation failure if OpenX402 is unavailable or rejects the transaction
- Malformed properties input may result in unexpected response or error
- Network timeout if the endpoint is temporarily unreachable

## 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 SKU identifier ('inventgap3'), a descriptive title ('Invent Gap 3'), the price ('$0.02'), and a diagnostic note confirming the paid response shape. Unpaid requests receive HTTP 402 with EIP-3009 payment requirement extras instead.
