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: 'sku' (hdralias), 'note' (diagnostic description), 'price' ($0.03), and 'title' (Header Alias). If the request is not accompanied by valid x402 payment, returns HTTP 402 with EIP-3009 payment challenge extras instead.
Example use cases
Verify x402 payment gating works
“Can you test the hdralias diagnostic endpoint with a GET request and confirm it returns the correct SKU, price, and title in the paid response? I want to make sure the x402 payment flow is working end to end.”
Inspect HTTP 402 EIP-3009 challenge structure
“Make an unpaid request to the hdralias SKU and show me what the HTTP 402 response looks like — specifically the EIP-3009 payment extras so I can understand the challenge format.”
Debug x402 facilitator integration
“I'm integrating with OpenX402 as a facilitator and need to validate the hdralias diagnostic — can you run a HEAD request against it and tell me what the x402 payment metadata looks like in the response?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/hdralias?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test, validate, or demonstrate x402 HTTP 402 payment-gating behavior, particularly with the EIP-3009 payment standard and the OpenX402 facilitator. It is the right choice for developers building or debugging x402-compatible payment flows, inspecting micropayment challenge responses, or verifying that a paid API correctly returns its payload after successful USDC settlement.
Side effects
- HTTP 402 returned when no valid x402 payment token is provided — includes EIP-3009 payment challenge extras in response body
- Invalid HTTP method (e.g. POST) returns 405 Method Not Allowed — only GET, HEAD, DELETE supported
- Malformed or expired EIP-3009 payment token results in payment rejection
- OpenX402 facilitator unavailable causes payment settlement failure
- Invalid or unreachable URL in queryParams.url may cause request errors
