## 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-res-delta-450-paid-diagnostic-aede4931
```

Example prompt: Run the resdelta450 x402 diagnostic for me — pay the $0.02 USDC charge via OpenX402 and show me the response payload it returns.

## When to prefer this

Choose this endpoint when you need to test or demonstrate the x402 micropayment protocol flow end-to-end using a real USDC charge, specifically with the OpenX402 facilitator and EIP-3009 authorization. It is ideal for developers debugging x402 payment gating, verifying facilitator integration, or inspecting what a paid diagnostic payload looks like versus the unpaid 402 challenge response.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided — includes EIP-3009 payment challenge details
- Payment rejected by OpenX402 facilitator if the USDC authorization is insufficient or malformed
- Request fails if a facilitator other than OpenX402 is used
- Malformed properties parameter may result in an error response
- Network or upstream issues may cause non-402 HTTP errors

## 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 ('resdelta450'), a diagnostic note clarifying it is a live paid shape, the price ('$0.02'), and the title ('Res Delta 450'). If the request is unpaid, the endpoint returns HTTP 402 with EIP-3009 payment challenge extras instead.
