## When to prefer this

Choose this endpoint when you need to test or validate x402 micropayment gating behavior specifically with the OpenX402 facilitator, or when you want a reference paid SKU diagnostic to confirm correct HTTP 402 and eip3009 response structure in a development or integration context.

## Known failure modes

- HTTP 402 returned with eip3009 extras when payment has not been made or is invalid
- Incorrect facilitator used (only OpenX402 is supported) leading to payment rejection
- Malformed or missing properties parameter may result in unexpected response
- Network timeout or unavailability of openclawproductions.com host

## How this service works
