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 (identifier 'benchcard'), note (diagnostic description), price ('$0.20'), and title ('Bench Card'). This confirms a successful x402 micropayment was processed via the OpenX402 facilitator and EIP-3009 authorization was accepted.

Example use cases

Agent payment integration smoke test

“I just wired up my AI agent to handle x402 micropayments — can you hit the bench card endpoint with a $0.20 USDC payment and show me the full response so I know the EIP-3009 authorization is going through correctly?”

Debugging a 402 rejection loop

“My agent keeps getting HTTP 402 errors when calling paid APIs. Can you probe the x402 bench card diagnostic for me and tell me what the EIP-3009 extras look like in the response so I can compare it to what my wallet is sending?”

OpenX402 facilitator compliance check

“I need to confirm that OpenX402 is properly routing my paid request — please call the bench card endpoint and verify the returned SKU and price match the expected $0.20 bench card shape.”

When to prefer

Use this endpoint when you need to validate that an x402 micropayment pipeline — specifically using the OpenX402 facilitator and EIP-3009 USDC authorization — is functioning correctly. Ideal for agent developers testing wallet integrations, debugging 402 payment flows, or confirming end-to-end USDC micropayment compliance before deploying to production paid endpoints.

Side effects

HTTP 402 returned with EIP-3009 extras when no valid payment header is provided
Payment rejected if facilitator is not OpenX402
Invalid or expired EIP-3009 authorization token causes payment failure
Network timeout if OpenX402 facilitator is unreachable
Malformed response if payment is partially processed
