How this service works
Health and payment-path check. Returns server time and confirms the x402 payment settled. The cheapest endpoint in the catalog at $0.001, intended for testing a client's payment flow.
Output
Returns the current server timestamp and a confirmation message indicating that the x402 micropayment was received and settled, effectively proving end-to-end that the payment client and gateway are functioning correctly.
Example use cases
Pre-flight payment flow check
“Before we start using any of the paid AI tools, can you ping the cheapest tariffmonkee endpoint to make sure my x402 payment client is set up correctly and payments are going through?”
Debugging a broken payment client
“My x402 micropayment integration isn't working and I'm not sure why — can you hit the tariffmonkee paid ping endpoint for me so we can see if the payment settles and the server confirms it?”
Periodic payment gateway health monitoring
“Every few minutes, can you ping tariffmonkee's paid ping endpoint to confirm that x402 payments are still being accepted and the server is responding with a current timestamp?”
Technical details
Endpoint
GEThttps://tariffmonkee.com/paid/ping?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the cheapest possible real-money test of an x402 micropayment integration — it costs only $0.001 USDC and is purpose-built for validating payment flows before invoking more expensive paid APIs. Ideal for debugging client configuration, pre-flight checks in automated workflows, or monitoring payment gateway availability.
Side effects
- Payment not settled — x402 payment header missing or malformed, returns 402 Payment Required
- Server unreachable — network or infrastructure issue, returns connection error
- Invalid payment amount — USDC value below $0.001 threshold, payment rejected
- Expired payment — payment token timestamp too old, returns 402
- Rate limiting — too many rapid pings from the same client
