The GoogleSearch tool lets an agent search the web through Google’s Programmable Search Engine.

​
Overview

The GoogleSearch tool is a tool that allows you to search the web using the GoogleSearch API. 
pip install langchain-community langchain-google-community

export GOOGLE_CSE_ID="${GOOGLE_CSE_ID:?Set GOOGLE_CSE_ID in your shell}"
export GOOGLE_API_KEY="${GOOGLE_API_KEY:?Set GOOGLE_API_KEY in your shell}"

import os 
from langchain_google_community import GoogleSearchAPIWrapper
from praisonaiagents import Agent, AgentTeam

data_agent = Agent(instructions="Search about best places to visit in India during Summer", tools=[GoogleSearchAPIWrapper])
editor_agent = Agent(instructions="Write a blog article")
agents = AgentTeam(agents=[data_agent, editor_agent], process='hierarchical')
agents.start()
Generate your GoogleSearch API key from Google CloudConsole by clicking on Create Credentials To get a CSE ID, Create a Google Programmable Search Engine here From the Overview of your newly created search engine copy the “Search engine ID”

How It Works

​
Getting Started

1

  3. Run the agent example in Overview
2

With Configuration

Use the same tool with an agent — see the Overview example, or pass env vars from the sections above.

​
Best Practices

Set GOOGLE_API_KEY and GOOGLE_CSE_ID in your shell or .env. GoogleSearchAPIWrapper reads them automatically — never hard-code them.
The Programmable Search API has a free daily query cap. Cache repeated queries and cap results so agents do not exhaust the quota mid-task.
Some queries return no results or hit quota errors. Wrap the call in try/except so the agent can fall back to another search tool.
