How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the SKU name ('hdrgrade'), a human-readable title ('Header Grade'), the price ('$0.02'), and a diagnostic note confirming the paid response shape. Without a valid x402 payment, returns HTTP 402 with EIP-3009 payment requirement extras.
Example use cases
Validating x402 payment flow end-to-end
“I'm integrating x402 micropayments into my app — can you call the OpenClaw hdrgrade endpoint and confirm that the payment handshake with OpenX402 completes successfully and returns the paid JSON shape?”
Inspecting EIP-3009 402 response structure
“I need to see exactly what HTTP headers and JSON body come back when an x402 endpoint returns a 402 with EIP-3009 extras — can you hit the hdrgrade SKU without payment first so I can inspect the unpaid response?”
Confirming OpenX402 facilitator is live
“Can you probe the OpenClaw hdrgrade diagnostic to check that the OpenX402 facilitator is online and properly gating access behind a $0.02 USDC payment?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/hdrgrade?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or demonstrate the x402 HTTP payment protocol with a real live endpoint, specifically to observe EIP-3009 payment-gating behavior, validate OpenX402 facilitator settlement, or inspect the paid vs unpaid response shapes for the hdrgrade diagnostic SKU. Not suitable for production data retrieval or non-x402 payment testing.
Side effects
- HTTP 402 returned when no valid x402 payment header is present — includes EIP-3009 extras describing payment requirements
- Payment rejected if USDC amount is incorrect or authorization is malformed
- OpenX402 facilitator unavailable — endpoint may return 5xx or timeout
- Invalid or missing 'properties' parameter may result in malformed request
- Network timeout if facilitator settlement is delayed
