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 diagnostic fields: sku ('capslice'), a note confirming it is a paid response shape, the price ('$0.16'), and a title ('Cap Slice'). Unpaid requests receive HTTP 402 with eip3009 payment extras instead.
Example use cases
Verify x402 payment gating on live endpoint
“I need to confirm that hitting the capslice endpoint without payment returns an HTTP 402 with eip3009 extras — can you probe it and show me what the unpaid response looks like?”
Confirm paid payload after USDC settlement
“After paying the $0.16 USDC via OpenX402, fetch the capslice diagnostic and confirm I'm getting back the correct SKU, title, and price in the JSON response.”
Integration smoke test for x402 facilitator
“Run a quick smoke test on the OpenX402 facilitator using the capslice SKU — I want to make sure the full payment flow from 402 challenge to paid response is working end to end.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/capslice?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or demonstrate a live x402 micropayment flow using the OpenX402 facilitator specifically, and want a simple, well-defined diagnostic payload (capslice SKU) to verify that payment gating, HTTP 402 challenge/response, and eip3009 extras are all functioning correctly end-to-end.
Side effects
- HTTP 402 returned if payment is missing or invalid — response includes eip3009 payment extras for wallet to process
- Facilitator not recognized if a non-OpenX402 facilitator is used — request may be rejected
- Malformed properties parameter may result in unexpected response or error
- Network timeout or server unavailability returns no response
