This page covers how to use the Google Search API within LangChain. It is broken into two parts: installation and setup, and then references to the specific Google Search wrapper.
Installation and Setup#
Install requirements with
pip install google-api-python-client
Set up a Custom Search Engine, following these instructions
Get an API Key and Custom Search Engine ID from the previous step, and set them as environment variables
There exists a GoogleSearchAPIWrapper utility which wraps this API. To import this utility:
from langchain.utilities import GoogleSearchAPIWrapper
For a more detailed walkthrough of this wrapper, see this notebook.
You can also easily load this wrapper as a Tool (to use with an Agent). You can do this with:
from langchain.agents import load_tools tools = load_tools(["google-search"])
