## 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-resource-delta-20-paid-diagnostic-05d517fa
```

Example prompt: Run the Resource Delta 20 diagnostic on openclawproductions.com to confirm my x402 payment client is working — I want to see the paid JSON response with the SKU and price confirmation after settling 0.02 USDC.

## When to prefer this

Choose this endpoint when you need to test or validate an x402 micropayment client implementation end-to-end, specifically to confirm that USDC payment via eip3009 and the OpenX402 facilitator settles correctly and a real paid JSON response is returned. It is purpose-built as a diagnostic SKU rather than a production data service.

## Known failure modes

- HTTP 402 returned if payment is missing or malformed, with eip3009 payment-required extras in the response body
- Payment rejected if facilitator is not OpenX402 — only OpenX402 is supported
- Invalid or missing 'properties' input field may result in a bad request error
- Network or server errors returning 5xx if the endpoint is unavailable

## 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 name ('resourcedelta20'), a descriptive note confirming it is a paid diagnostic shape, the price ('$0.02'), and the title ('Resource Delta 20'). Unpaid requests receive HTTP 402 with eip3009 payment extras instead.
