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 ('proofledger'), a human-readable title ('Proof Ledger'), the price ('$0.22'), and a diagnostic note confirming the paid JSON shape. If payment has not been provided, the endpoint returns HTTP 402 with EIP-3009 payment-required metadata instead.
Example use cases
Verify x402 payment flow end-to-end
“I want to confirm my x402 integration is working — can you call the proofledger endpoint, pay the $0.22 USDC through OpenX402, and show me the paid response so I know the EIP-3009 payment gate opened correctly?”
Debug 402 response before payment
“Can you probe the proofledger diagnostic endpoint without sending payment so I can see exactly what the HTTP 402 response looks like with the eip3009 extras before I wire up my payment logic?”
Confirm OpenX402 facilitator is live
“I need to verify that the OpenX402 facilitator is operational — hit the x402-tools proofledger SKU and tell me whether it returns a valid paid response or errors out.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/proofledger?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test, diagnose, or demonstrate the x402 HTTP payment gating protocol with EIP-3009 extras specifically via the OpenX402 facilitator. It is ideal for developers integrating x402 into their own APIs who want a live reference endpoint that returns a predictable paid payload. Prefer this over generic HTTP testing tools when the goal is to validate USDC micropayment flows or inspect 402-with-eip3009 response structures.
Side effects
- HTTP 402 returned when no valid x402 payment token is included — response includes eip3009 extras describing payment requirements
- Payment token invalid or expired — facilitator rejects and 402 is re-issued
- OpenX402 facilitator unavailable — request cannot be settled
- Malformed properties parameter — may result in unexpected response or error
- USDC balance insufficient to cover $0.22 per-call cost
