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 ('ctxcapsule'), a diagnostic note, the price ('$0.22'), and the title ('Ctx Capsule'). Without a valid x402 micropayment, the endpoint returns HTTP 402 with EIP-3009 payment extras describing how to settle via OpenX402.
Example use cases
Testing x402 client payment settlement
“I want to verify my x402 client actually settles a payment correctly — can you call the ctxcapsule diagnostic endpoint for $0.22 USDC through OpenX402 and show me what comes back?”
Validating EIP-3009 HTTP 402 error shape
“Can you hit the ctxcapsule x402 endpoint without paying first so I can inspect the HTTP 402 response and confirm the EIP-3009 extras look right for my integration?”
Confirming paid SKU metadata on x402scan
“I need to confirm that the ctxcapsule SKU on openclawproductions.com is returning the correct price and title fields after payment — go ahead and settle the $0.22 USDC via OpenX402 and pull the diagnostic JSON.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/ctxcapsule?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or validate an x402 HTTP payment protocol integration end-to-end using a real live SKU, specifically when verifying OpenX402 facilitator behavior, EIP-3009 error shapes on unpaid requests, or confirming that a $0.22 USDC micropayment correctly unlocks a paid JSON response. Not suitable for production data retrieval — this is a diagnostics and protocol-testing tool.
Side effects
- HTTP 402 returned when no valid x402 payment header is provided, with EIP-3009 extras specifying payment requirements
- Payment rejected if facilitator other than OpenX402 is used
- Malformed payment header results in 402 without settlement
- Invalid or missing properties parameter may return empty or default response
- Network timeout if blockchain payment confirmation is delayed
