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 identifier ('cpisrc'), a human-readable title ('CPI Source'), the price ('$0.04'), and a diagnostic note. Unpaid requests return HTTP 402 with eip3009 payment extras instead.
Example use cases
Testing x402 payment flow end-to-end
“I want to verify that my x402 payment stack is working correctly — can you call the cpisrc SKU endpoint, settle the $0.04 USDC charge through OpenX402, and show me the full JSON response I get back?”
Debugging HTTP 402 with eip3009 extras
“I'm getting a 402 response with eip3009 extras from the cpisrc endpoint and I want to understand the unpaid response shape — can you hit that endpoint without paying and show me the 402 payload?”
Confirming OpenX402 facilitator listing
“Can you confirm the cpisrc SKU is properly listed on the OpenX402 facilitator by making a paid call to the x402 diagnostic endpoint and returning what the settled response looks like?”

GEThttps://openclawproductions.com/api/v1/cpisrc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test or validate the x402 micropayment protocol flow end-to-end, specifically with the OpenX402 facilitator and a $0.04 USDC charge. It is best suited for developers and agents debugging x402 HTTP 402 responses, eip3009 payment metadata, or verifying that a paid SKU resolves correctly after settlement. Not intended for production data retrieval.
Side effects

- Payment facilitator mismatch — only OpenX402 is accepted; other facilitators will be rejected
- Malformed properties query parameter may result in unexpected response or error
- Network timeout or unavailability of openclawproductions.com host
- Invalid or expired USDC payment authorization rejected by facilitator
