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 name ('sigalias'), a diagnostic note, the price ($0.03), and a title field confirming the paid response shape. Unpaid requests return HTTP 402 with EIP-3009 payment extras instead.

Example use cases

Verify x402 payment gate setup

“Check whether my API at https://myapi.dev is correctly returning HTTP 402 with EIP-3009 payment details for unpaid requests — use the x402 sigalias diagnostic.”

Debug x402 facilitator integration

“I set up OpenX402 on my origin https://myservice.io — can you run the sigalias probe to confirm the x402 payment flow is working end-to-end?”

Inspect x402 response shape for compliance

“Run an x402 diagnostics check on https://openclawproductions.com using the sigalias SKU and show me what the paid response looks like so I can match it in my implementation.”

Technical details

Endpoint

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

When to prefer

Use this endpoint when you need to verify or debug x402 payment protocol compliance for a specific URL or origin, especially when working with OpenX402 as the facilitator. It is purpose-built for x402 diagnostics rather than general HTTP inspection or payment processing.

Side effects

HTTP 402 returned if payment is not included — response will contain EIP-3009 payment authorization extras
Invalid or unreachable URL in query parameters returns an error
Unsupported HTTP method (only GET, HEAD, DELETE allowed) returns a validation error
Non-x402-compatible origin URL may return unexpected diagnostic output
