Revert "Make serpapi base url configurable via env (#4402)" (#4750) 
This reverts commit 5111bec540.

This PR introduced a bug in the async API (the `url` param isn't bound);
it also didn't update the synchronous API correctly, which makes it
error-prone (the behavior of the async and sync endpoints would be
different)

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)

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"])

For more information on this, see this page
