## 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-soft-pass-231-diagnostic-endpoint-607d3c22
```

Example prompt: Run the x402 Soft Pass 231 diagnostic for me — I want to verify my eip3009 payment authorization is working correctly against the OpenX402 facilitator.

## When to prefer this

Use this endpoint when you need to test, debug, or validate an x402 HTTP payment protocol integration — specifically for eip3009-based USDC micropayments handled by the OpenX402 facilitator. It is ideal as a low-cost ($0.02) canary call to verify your payment headers, authorization tokens, and facilitator configuration are correct before hitting higher-value endpoints.

## Known failure modes

- HTTP 402 returned if no valid x402 payment token is provided, with eip3009 extras describing payment requirements
- Payment amount mismatch causes 402 rejection
- Wrong facilitator (non-OpenX402) may result in payment rejection
- Malformed eip3009 authorization leads to 402 error
- Network timeout if payment settlement takes too long

## 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 ('softpass231'), a human-readable diagnostic note, the price ($0.02), and the title ('Soft Pass 231'). Unpaid or incorrectly authorized requests receive an HTTP 402 response with eip3009-formatted payment requirement details.
