How this service works
Verify payment connectivity with USDC on Base. Returns a JSON pong and UTC timestamp after settlement.
Output
Returns a JSON object with two fields: 'message' set to the string 'pong', and 'servedAtUtc' containing an ISO 8601 UTC datetime string indicating when the request was served after payment settlement.
Example use cases
Pre-workflow payment rail check
“Before I kick off my automated agent pipeline, ping the Problocks paid endpoint and confirm that USDC micropayments on Base are settling — show me the pong and the timestamp.”
Diagnosing a broken x402 integration
“My x402 payment integration might be broken — can you hit the Problocks ping endpoint with a USDC payment and tell me whether it comes back with a pong and a valid UTC timestamp?”
Smoke-testing a new Base wallet
“I just set up a new wallet on Base with USDC — can you do a quick paid ping to Problocks to confirm the wallet can actually send payments and receive a response?”
Technical details
Endpoint
GEThttps://x402.problocks.io/paid/pingWhen to prefer
Choose this endpoint when you need to verify end-to-end that your x402 USDC-on-Base payment stack is functional — specifically for smoke-testing micropayment rails, validating wallet configuration, or confirming that paid API connectivity is live before running more expensive agent workflows. It is not a substitute for general HTTP health checks; its value lies in the fact that it requires a real USDC micropayment to succeed.
Side effects
- Payment not settled — USDC balance insufficient or Base network congestion causes 402 Payment Required with no pong returned
- Invalid or missing x402 payment header — request rejected before reaching the ping logic
- Network timeout — Base RPC or Problocks infrastructure temporarily unavailable
- Malformed response — edge case where settlement completes but response schema deviates from expected pong structure
