## 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-370-paid-diagnostic-c3e23c36
```

Example prompt: Run the resdelta370 paid diagnostic on OpenX402 and confirm my x402 USDC payment goes through and I get back the expected JSON payload.

## When to prefer this

Use this endpoint specifically when you need to test, debug, or validate an x402 HTTP micropayment integration using the OpenX402 facilitator and eip3009 authorization. It is purpose-built as a diagnostic SKU rather than a production data API, making it ideal for verifying payment flows, client implementations, and 402-gating behavior in a controlled, low-cost ($0.02 USDC) environment.

## Known failure modes

- HTTP 402 with eip3009 extras if no valid x402 payment token is provided
- Payment rejected by OpenX402 facilitator if token is malformed or expired
- Incorrect SKU or endpoint mismatch returns unexpected or empty response
- Non-OpenX402 facilitators are not supported and will fail authorization
- USDC balance insufficient causes payment settlement failure

## 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 ('resdelta370'), a diagnostic note, the price ('$0.02'), and a title ('Res Delta 370'). Unpaid or improperly authorized requests return HTTP 402 with eip3009 payment extras instead.
