Google Search Wrapper

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 GOOGLE_API_KEY and GOOGLE_CSE_ID respectively

Wrappers

Utility

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.

Tool

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"])
