## 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`):

Example prompt: Can you call the freehostratio x402 diagnostic endpoint to verify the micropayment gating is working correctly and show me the JSON payload it returns after settling the $0.02 USDC fee?

## When to prefer this

Use this endpoint when you need to test or demonstrate the x402 micropayment protocol in action, specifically to verify that HTTP 402 gating with eip3009 extras and OpenX402 facilitation is functioning correctly for the freehostratio SKU. Not a production data source — best suited for x402 integration testing and diagnostics.

## Known failure modes

- HTTP 402 with eip3009 extras returned when no valid payment header is present
- Payment rejected if facilitator other than OpenX402 is used
- Malformed or missing properties parameter may yield unexpected response
- Network timeout or availability issues on openclawproductions.com
- USDC payment insufficient or signed incorrectly causing 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 name ('freehostratio'), a diagnostic note, the price ($0.02), and a title ('Free Host Ratio'). If called without a valid x402 payment, the endpoint returns HTTP 402 with eip3009 payment extras describing how to settle via OpenX402.
