SerpAPI
This page covers how to use the SerpAPI search APIs within LangChain. It is broken into two parts: installation and setup, and then references to the specific SerpAPI wrapper.
Installation and Setup
- Install requirements with
pip install google-search-results
- Get a SerpAPI api key and either set it as an environment variable (
SERPAPI_API_KEY
) - Optional, if you are using a proxy, set environment variable (
SERPAPI_BASE_URL
) or pass it to the LLM constructor to your proxy url.
Wrappers
Utility
There exists a SerpAPI utility which wraps this API. To import this utility:
from langchain.utilities import SerpAPIWrapper
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(["serpapi"])
