Feature request

Feature Request

We propose adding a new tool that integrates the YouTube Data API (YouTube Search API) into Langchain. This can take a query from an agent, use the YouTube Search API to gather relevant video information, format the information into a readable output, and return the result to the agent. The integration will support the ReAct pattern by allowing the LLM to decide when to invoke the YouTube search tool during reasoning steps.

Sample Usage

from langchain.agents import initialize_agent, Tool
from langchain.llms import OpenAI
from langchain_community.tools.youtube_search import YouTubeSearchTool

# Initialize the YouTube Search tool
youtube_tool = YouTubeSearchTool()

tools = [
    Tool(
        name="YouTube Search",
        func=youtube_tool.run,
        description="Useful for searching YouTube for videos related to a query.",
    ),
]

llm = OpenAI(temperature=0)

agent = initialize_agent(tools, llm, agent="zero-shot-react-description", verbose=True)

agent_response = agent.run("Find me tutorials on Python programming.")
print(agent_response)

Motivation

Motivation

There are various API integrations for useful tasks, and we would like to expand it for an agent to be able to search through YouTube videos using the official API (https://developers.google.com/youtube/v3/docs/search) for enhanced responses and querying capabilities.

Proposal (If applicable)

Proposal

We plan to open a PR to add a new tool that allows access to the YouTube Search API (https://developers.google.com/youtube/v3/docs/search), which will allow the agent to access YouTube search results and information about the corresponding video, channel, and playlists. This can be extended with the other YouTube APIs to fetch information about the transcript, comment section, and in-depth channel information.

We currently have an open issue here: #27349
