How this service works
Test endpoint for verifying x402 payment integration end to end. Returns a static greeting in the Agent Tollbooth standard response envelope. Not a data product — use it to smoke-test your x402 client for $0.001 before calling our compliance endpoints: OFAC sanctions screening ($0.01) and FDIC bank verification ($0.01), listed under this same payTo address.
Output
A static greeting string wrapped in the Agent Tollbooth standard response envelope, confirming that the x402 payment was accepted and the client integration is functioning correctly.
Example use cases
Validate x402 payment integration
“Before we start using the compliance API, can you run a quick test payment through the Tollbooth endpoint to make sure our x402 setup is working and we're ready to go?”
Smoke test agent's micropayment wallet
“I want to verify our agent can actually send and receive USDC payments—can you hit the Hello endpoint with a tiny test transaction so we know the wallet is properly configured?”
Confirm payment client ready for production
“We're about to deploy our agent to production with x402 payments enabled. Can you do a sanity check by calling the Tollbooth Hello endpoint first to confirm everything's connected correctly?”
