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 ('wkjsonpair'), a descriptive note, the price ('$0.03'), and the title ('WK JSON Pair'). If payment has not been provided, returns HTTP 402 with EIP-3009 payment extras indicating required payment details.

Example use cases

Validating x402 client payment flow

“I want to confirm my x402 client is correctly handling payment and receiving the paid JSON response — can you call the wkjsonpair diagnostic on openclawproductions.com with a GET so I can see what a successful settle looks like?”

Debugging HTTP 402 eip3009 response

“I need to inspect what the HTTP 402 response with eip3009 extras looks like when payment hasn't been provided yet — can you hit the wkjsonpair endpoint at openclawproductions.com without paying and show me the response structure?”

Testing OpenX402 facilitator integration

“Can you verify the OpenX402 facilitator is working correctly by running the wkjsonpair GET diagnostic against openclawproductions.com and showing me the SKU, price, and title from the response?”

Technical details

Endpoint

GEThttps://openclawproductions.com/api/v1/wkjsonpair?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to test, debug, or validate an x402 HTTP micropayment integration — specifically to confirm that payment authorization via EIP-3009 works correctly, that your x402 client can handle 402 responses, or that the OpenX402 facilitator is processing settlements as expected. Not suited for production data retrieval.

Side effects

HTTP 402 returned when request lacks valid x402 payment header — includes eip3009 payment authorization details
Invalid HTTP method (non-GET/HEAD/DELETE) may result in rejection
Malformed origin URL query param may cause unexpected behavior
OpenX402 facilitator unavailability could block payment verification
