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 openclaw-x402-llms-version-path-diagnostics-a7f41397
```

Example prompt: Run the x402 paid diagnostics on the openclawproductions.com LLMs version path endpoint using a GET request and tell me what SKU metadata and pricing info comes back after payment.

## When to prefer this

Choose this endpoint when you specifically need to test or audit x402 micropayment gating on the openclawproductions.com LLMs version path, verify EIP-3009 payment challenge responses, or confirm OpenX402 facilitator integration. It is a diagnostic/probe tool, not a general-purpose API — prefer it for x402 compliance checks, payment flow testing, or SKU metadata retrieval rather than for obtaining LLM model information directly.

## Known failure modes

- HTTP 402 returned when payment has not been settled via x402 — includes EIP-3009 payment challenge extras
- Facilitator other than OpenX402 not accepted, resulting in payment rejection
- Invalid or unsupported HTTP method (only GET, HEAD, DELETE allowed) causes request failure
- Malformed origin URL parameter may result in error or defaulting to https://openclawproductions.com
- Network or server errors from openclawproductions.com infrastructure

## 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 ('llmsverpath'), a human-readable title ('LLMs Ver Path'), the price ('$0.02'), and a diagnostic note. Unpaid requests receive HTTP 402 with EIP-3009 payment challenge extras instead.
