How this service works
Returns the message you send, with its length and the server time. Use to test an x402 client, payment flow or agent tool wiring end to end.
Output
Returns a JSON object containing the original message string, its character length as a number, and the ISO 8601 timestamp at which the server received it.
Example use cases
Verify x402 payment integration
“Can you ping the Agent Data Tools echo endpoint with the message 'test123' so I can confirm my USDC payment on Base is actually flowing through before I use the real tools?”
Check API connectivity before agent run
“Before I start my agent workflow, send a quick echo request to Agent Data Tools with the message 'ping' so I know the service is up and responding.”
Measure round-trip latency
“Send the message 'latency check' to the Agent Data Tools echo endpoint and report back the receivedAt timestamp so I can see how fast the round trip is.”

It is the lowest-risk, lowest-cost probe available on this platform.
