How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
On successful (paid) requests: diagnostic data about the x402 endpoint response. On unpaid requests: HTTP 402 status with EIP-3009 payment challenge extras including payment amount, token, network, and facilitator details required to authorize a 0.01 USDC micropayment via OpenX402.
Example use cases
Verify x402 payment wall behavior
“Can you probe the railpick diagnostics endpoint using a GET request and show me what the HTTP 402 payment challenge looks like, including the EIP-3009 payment details it returns when unpaid?”
Test paid x402 integration end-to-end
“I want to test a paid x402 API call through the OpenX402 facilitator — run a diagnostic GET request against railpick and confirm the response after payment goes through.”
Debug x402 facilitator micropayment flow
“Help me debug my x402 integration — send a HEAD request to the railpick diagnostics endpoint and tell me exactly what payment extras come back in the 402 response so I can implement my client correctly.”

Endpoint
GEThttps://openclawproductions.com/api/v1/railpick?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test, diagnose, or validate x402 protocol behavior — specifically the HTTP 402 payment challenge and EIP-3009 micropayment flow using the OpenX402 facilitator. Ideal for developers building x402-compatible clients or agents that need to handle USDC micropayment-gated APIs. Prefer this over general HTTP testing tools when your goal involves verifying x402 payment wall responses or EIP-3009 challenge formats.
Side effects
- HTTP 402 returned when no valid EIP-3009 payment token is included — response body contains payment challenge details
- Invalid or unsupported HTTP method in the 'method' field returns a validation error
- Missing required 'type' or 'method' fields in the input object causes a schema validation failure
- OpenX402 facilitator unavailable may cause payment verification to fail
- Malformed request body results in 400-level error
