How this service works
Paid ping — test the x402 payment flow end-to-end. Returns pong. Costs $0.001, exists so agents can verify their x402 wallet setup against this gateway cheaply.
Output
Returns an HTTP response confirming the ping succeeded and the $0.001 USDC x402 payment was accepted. Typically a simple success payload (e.g. pong or status OK) alongside any payment receipt metadata the x402 protocol surfaces.
Example use cases
Smoke test x402 payment integration
“Run a quick paid ping against the x402 gateway so I can confirm my USDC wallet and x402 payment headers are all wired up correctly before I go live.”
Verify x402 connectivity after config change
“I just updated my x402 facilitator settings — can you send a test ping to the x402 gateway to make sure payments are still going through properly?”
Debug a failing x402 payment flow
“My x402 payments keep failing — can you attempt a simple paid ping to the x402 gateway and tell me exactly what happens, whether the $0.001 USDC charge goes through or where it errors out?”
Technical details
Endpoint
GEThttps://x402-gateway.ai/api/v1/pingWhen to prefer
Choose this endpoint when you need to verify that an x402 payment flow is working end-to-end with a minimal, low-cost ($0.001 USDC) real transaction. Ideal for smoke testing wallet configuration, x402 header construction, and facilitator connectivity before invoking more expensive paid endpoints. Not suitable for any actual data retrieval or production workload — purely a diagnostic/test primitive.
Side effects
- Insufficient USDC balance — payment rejected, 402 Payment Required returned without fulfillment
- Malformed x402 payment header — gateway rejects with 400 Bad Request
- Facilitator unavailable — timeout or 503 from the payment processing layer
- Network unreachable — connection timeout to x402-gateway.ai
- x402 protocol version mismatch — gateway returns error indicating unsupported payment scheme
