How this service works
Returns pong with the server time and an optional echo string, after a real x402 USDC payment on Base. Useful for testing that an agent's x402 payment client, wallet, and budget limits work end to end before using costlier services, and for monitoring. The cheapest paid call VerifyLite offers.
Output
Returns a JSON object containing a 'pong' acknowledgement, the server's current UTC timestamp, and the echoed input string if one was provided. Confirms a successful real USDC payment on Base was processed.
Example use cases
Smoke test before agent deployment
“Before I deploy my agent to production, send a live x402 ping with the echo text 'pre-deploy check' so I can confirm the payment client, wallet, and budget limits are all working correctly.”
Debugging a broken payment client
“My x402 payment integration isn't behaving as expected — can you send a real USDC ping to VerifyLite with the echo 'debug-run' and tell me the server time you get back so I can verify the full payment round-trip?”
Confirming budget cap enforcement
“I just set a $0.01 daily spending limit on my agent wallet — ping VerifyLite with the message 'budget test' using a real x402 payment so I can see if the budget cap kicks in after 10 calls.”
Technical details
Endpoint
POSThttps://verifylite.hydratinghealingtouch.workers.dev/ping?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when you need to validate that an agent's x402 payment client, wallet credentials, and USDC budget limits are functioning correctly end to end with a real on-chain transaction. It is the cheapest and simplest x402-gated endpoint available for integration smoke tests, costing only $0.001 USDC per call. Prefer it over production endpoints when the goal is testing payment infrastructure rather than consuming a real capability.
Side effects
- Insufficient USDC balance in agent wallet causes payment failure
- x402 client misconfiguration results in rejected payment header
- Echo string exceeding 256 characters is rejected
- Network or Cloudflare Worker downtime returns a 5xx error
- Wallet not connected to Base mainnet causes payment to fail
