## 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-506-paid-diagnostic-36b8ad14
```

Example prompt: Run the Res Delta 506 x402 diagnostic on openclawproductions.com and show me the paid JSON response — I want to confirm the EIP-3009 payment flow through OpenX402 is working correctly.

## When to prefer this

Choose this endpoint when you need to test or validate the x402 HTTP micropayment protocol end-to-end using EIP-3009 and USDC via the OpenX402 facilitator. It is ideal for developers integrating x402 payment flows who need a known, low-cost ($0.02) live diagnostic target to confirm payment gating, 402 error shapes, and successful settlement behavior.

## Known failure modes

- HTTP 402 returned with EIP-3009 payment instructions when no valid payment is provided
- Payment facilitator mismatch — only OpenX402 is accepted; other facilitators will be rejected
- Malformed EIP-3009 authorization results in payment rejection
- Network errors or endpoint unavailability returning non-402 HTTP errors
- Invalid or expired USDC payment token causing authorization 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 ('resdelta506'), a human-readable title ('Res Delta 506'), the price ('$0.02'), and a diagnostic note. Unpaid requests return HTTP 402 with EIP-3009 payment metadata in the response extras.
