Open In Colab Open on GitHub The DuckDuckGo search integration allows users to perform real-time web searches within the AG2 framework using the DuckDuckGo search engine. Follow these steps to integrate DuckDuckGoSearchTool with AG2 Agents.

​
Configuration

DuckDuckGo Search does not require an API key, making it simple to set up.

​
Package Installation

To get started with the DuckDuckGo Search integration in AG2, you need to install the necessary package: Install AG2 with openai and duckduckgo extras: 
pip install -U "ag2[openai] duckduckgo_search"
Note: If you have been using autogen or ag2, all you need to do is upgrade it using: 
pip install -U "autogen[openai] duckduckgo_search"
or 
pip install -U "ag2[openai] duckduckgo_search"
as autogen, and ag2 are aliases for the same PyPI package.
You’re all set! Now you can start using DuckDuckGo Search with AG2.

​
Implementation

The DuckDuckGoSearchTool enables agents to perform real time web searches.

​
Imports

import os

from autogen import AssistantAgent, UserProxyAgent
from autogen.tools.experimental import DuckDuckGoSearchTool

​
Agent Configuration

Configure an assistant agent and user proxy to be used for LLM recommendation and execution respectively. 
os.environ["AUTOGEN_USE_DOCKER"] = "False"

from autogen import LLMConfig

# Configure your LLM settings. You can use OAI_CONFIG_LIST_sample as a template.
config_list = LLMConfig.from_local("OAI_CONFIG_LIST", api_type="openai", model="gpt-4o-mini")

assistant = AssistantAgent(
    name="assistant",
    llm_config=config_list,
)

user_proxy = UserProxyAgent(name="user_proxy", human_input_mode="NEVER")

​
Tool Setup

# Initialize the DuckDuckGoSearchTool. No API key is needed.
duckduckgo_search_tool = DuckDuckGoSearchTool()

# Register the tool for LLM recommendation and execution.
duckduckgo_search_tool.register_for_llm(assistant)
duckduckgo_search_tool.register_for_execution(user_proxy)

​
Start the Conversation

With the setup complete, you can now use the assistant to fetch live web search results using DuckDuckGo. 
response = user_proxy.initiate_chat(
    recipient=assistant,
    message="What happened with stock prices after deepseek was launched? Please search the web using DuckDuckGo.",
    max_turns=2,
)
print(f"Final Answer: {response.summary}")
