load_dotenv()

researcher = Agent(
    role="Research Agent",
    goal="Access and summarize gated web content by paying for it when needed",
    backstory=(
        "You are a research agent that can pay for gated content using "
        "Xenarch micropayments. When you encounter a payment gate, you "
        "check the price, pay with USDC on Base, and use the access token "
        "to retrieve the content."
    ),
    tools=[check_gate, pay, get_history],

    ),
    expected_output="A summary of the gate status and any payment made.",
