## How to call it through Zero

```

Example prompt: Can you do a quick ping to tariffmonkee's paid endpoint to confirm my x402 USDC payment flow is working before we call the more expensive tools?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Health and payment-path check. Returns server time and a confirmation that your x402 payment settled. Cheapest endpoint in the catalog; use it to verify your client's payment flow before calling paid tools.

## 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.
