How this service works
Cheapest possible paid call: proves your wallet, our 402, and the receipt path work. Returns pong and a timestamp.
Output
Returns a 'pong' confirmation string and a server-side timestamp, plus a payment receipt confirming the $0.001 USDC micropayment was processed. Useful for verifying the full x402 payment round-trip is functioning.
Example use cases
Bootstrapping a new x402 wallet integration
“I just set up a new crypto wallet for my agent — can you do a quick $0.001 paid ping to Flipvo's tollbooth to verify the x402 payment and receipt flow all go through correctly?”
Pre-flight check before a paid agent workflow
“Before my agent starts making real paid API calls, run a cheap test ping against the Flipvo tollbooth to make sure the wallet auth and 402 receipt path are both working.”
Debugging a broken payment receipt path
“My agent's x402 receipt handling seems broken — can you fire a minimal paid POST to the Flipvo tollbooth and tell me whether the pong and timestamp come back properly?”
