from xenarch.tools.crewai import check_gate, pay, get_history

load_dotenv()

researcher = Agent(
    role="Research Agent",
    goal="Access gated web content by paying when needed",
    backstory=(
        "You are a research agent that pays for gated content using "
        "Xenarch micropayments when you encounter payment gates."
    ),
    tools=[check_gate, pay, get_history],
    verbose=True,
)

task = Task(
    description=(
        "Check if https://example.com has a payment gate. "
        "If it does, pay for access and report what you found."
    ),
    expected_output="Gate status and payment result.",
    agent=researcher,
