## 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 openclaw-x402-grid-sched-diagnostics-94aa1130
```

Example prompt: Run the gridsched diagnostic on the OpenClaw x402 tools endpoint — I want to verify the paid x402 flow works end-to-end with the OpenX402 facilitator using 0.05 USDC.

## When to prefer this

Use this endpoint when you need to test, validate, or debug an x402 HTTP payment-gating integration using EIP-3009 and the OpenX402 facilitator. It is ideal for developers verifying that their USDC micropayment flow correctly unlocks a paid API response, or for probing what a 402 rejection payload looks like before implementing a full x402 client.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided — includes EIP-3009 extras specifying payment requirements
- Invalid or malformed payment authorization results in rejected transaction
- OpenX402 facilitator unavailable causes payment verification to fail
- Incorrect USDC amount in payment header triggers 402 rejection

## 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 name ('gridsched'), a diagnostic note confirming it is a paid example shape, the price ($0.05), and the endpoint title ('Grid Sched'). On unpaid requests, returns HTTP 402 with EIP-3009 payment extras indicating how to pay.
