How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a Lightning Network payment quote including pricing details and EIP-3009 payment extras required to authorize a paid x402 API call. Unpaid requests receive an HTTP 402 response with payment requirements embedded in the response headers/body.
Example use cases
Pre-flight cost check before paid API call
“Before I make that paid API call, can you fetch me a Lightning quote for a GET request so I know exactly how much it'll cost in USDC?”
Diagnosing x402 payment flow
“I'm testing an x402-enabled endpoint — can you pull a Lightning quote for a POST request and show me the EIP-3009 payment details I'll get back?”
Automating micropayment workflow
“I need to automate payments for repeated API calls — can you grab an lnquote for a GET request so my agent can handle the $0.02 USDC payment before each call?”
