Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-v1extskip-paid-diagnostic-f1d193df
```

Example prompt: Run an x402 paid diagnostic on my API endpoint at https://example.com using a GET request and tell me if the 402 payment flow and EIP-3009 extras are working correctly.

## When to prefer this

Choose this endpoint when you need to test, validate, or debug x402 protocol compliance specifically using the OpenX402 facilitator and EIP-3009 micropayment mechanics. It is purpose-built for x402 developers and integrators who want to confirm that HTTP 402 payment gating, SKU responses, and EIP-3009 extras are functioning correctly on their own or a third-party endpoint. Prefer this over generic HTTP probing tools when x402 protocol compliance is the explicit goal.

## Known failure modes

- HTTP 402 returned if payment not provided — expected behavior for unpaid calls, includes EIP-3009 payment extras
- Invalid or unreachable URL input may return an error or empty diagnostic
- Non-OpenX402 facilitators not supported — requests via other facilitators will fail
- Only GET, HEAD, and DELETE methods accepted — POST or PUT will be rejected
- Missing required 'type' or 'method' fields in input will cause schema validation failure

## 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 identifier ('v1extskip'), a diagnostic note, the price ('$0.03'), and a title ('V1 Ext Skip'). Unpaid requests return HTTP 402 with EIP-3009 payment extras; paid requests return the full diagnostic JSON payload confirming the x402 payment flow is operational.
