## Quick Start

<Steps>
  <Step title="Set API Key">
    Set your Perplexity API key as an environment variable in your terminal:

    ```bash theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
    export PERPLEXITY_API_KEY=your_perplexity_api_key_here
    ```
  </Step>

  <Step title="Create a file">
    Create a new file `perplexity_search.py` with the following code:

    ```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
    from praisonaiagents import Agent, MCP
    import os

    # Get API key from environment variable
    api_key = os.getenv("PERPLEXITY_API_KEY")

    agent = Agent(
        instructions="You are a helpful assistant that can search the web for information. Use the available tools when relevant to answer user questions.",
        llm="gpt-4o-mini",
        tools=MCP("uvx perplexity-mcp", 
            env={"PERPLEXITY_API_KEY": api_key, "PERPLEXITY_MODEL": "sonar" })
    )

    result = agent.start("What is the latest news on AI?, Pass only the query parameter to the tool")

    print(result)
    ```
  </Step>

  <Step title="Install Dependencies">
    Make sure you have the required packages installed:

    ```bash theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
    pip install "praisonaiagents[llm]"
