Hackathon integration test · $0.01 USDC or USDT0
Find out if your agent can buy real-world evidence.
A one-cent micro-payment tests discovery, payment, task creation, and polling. It returns a real task ID without pretending a physical visit happened.
What the test proves
Your agent reaches the live endpoint and reads the machine-priced challenge.
It authorizes exactly $0.01 in Arbitrum One USDC, Base USDC, or X Layer USDT0.
GroundTruth returns a real task ID and poll URL.
You verify the asynchronous status and evidence contract.
Fastest path
Hand this request to your agent.
The spending limit is explicit. A compatible wallet agent should stop for approval under its own policy, pay the challenge, and return the created task.
Works with Arbitrum One USDC, Base USDC, or X Layer USDT0 when the corresponding live facilitator is available. GroundTruth never asks for a private key or seed phrase.
Use GroundTruth to run an integration test.
