How to Build an AI Agent That Scrapes Google in Real-Time Using N8N + SerpAPI

In the past, accomplishing large projects often meant hiring big teams — one person for research, another for writing, someone else for analysis, and so on. Businesses ran on people power. But times have changed. The tools we have today are smarter, faster, and more capable than ever before. Relying solely on large teams isn’t always the most efficient option anymore. In fact, for many tasks that once required several hands, people are now turning to AI agents — self-operating systems that can handle tasks intelligently and independently.

This shift isn’t just a tech trend; it’s a complete change in how work gets done. Whether it’s collecting information, writing summaries, or generating insights — AI agents can now do it all with minimal human input. And the best part? You don’t need to be a machine learning expert to start building them.

If you’ve been curious about AI automation but didn’t know where to begin, you’re in the right place. This guide is designed to help you take your very first step. I’ll walk you through how to create a basic AI agent that can scrape real-time data from Google and present the result in a clean, easy-to-understand format. It’s a practical project — something you can use for your own needs, or even offer as a service to clients. The potential applications are endless, and once you get the hang of it, the sky’s the limit.

💡 What is an Agent?

In simple terms, an agent is an automation that performs a task on your behalf.

Just like a real estate agent finds a home for you, an AI agent fetches information from Google, processes it, and returns results – all automatically.

🚀 Tools We'll Use

• N8N – No-code/low-code automation builder
• OpenAI API – To generate the final response using ChatGPT
• SerpAPI – To scrape real-time data from Google

✅ Step-by-Step Setup

Step 1: Create an N8N Account

Go to n8n.io and sign up. You’ll get 1000 free executions on the trial plan. Create a new project (e.g., “Testing Agent”).

Step 2: Add Chat Trigger

Use Chat Trigger for quick testing. Later, you can connect this to WhatsApp, Telegram, or a webhook for real use cases.

Step 3: Add AI Agent Node

Search for “Advanced AI” and add the “AI Agent” node. In the model section, select:

• Provider: OpenAI
• Model: gpt-4o-mini

Generate an OpenAI API key from OpenAI Dashboard and paste it in credentials.

Step 4: Set Memory and Tool

Add simple memory with a 5-message context. Also, add the Calculator tool (useful for math-related queries).

Step 5: Set Up SerpAPI

Sign up at SerpAPI.com. Get your free API key (100 searches/month). Add a new “Google Search” node in N8N, paste the API key in credentials.

🔍 How Does It Work?

It’s super simple and seamless — here’s what happens behind the scenes:

Let’s say you type a question like, “What’s the weather today in Tokyo?”

The moment you hit enter, a smart tool called SerpAPI jumps into action. It quickly pulls fresh, real-time data straight from Google — just like a virtual assistant scanning the web for you instantly.

Then, that raw data is handed over to OpenAI, which acts like your intelligent interpreter. It takes all that information, filters out the noise, understands the context, and turns it into a clear, conversational response — no messy links or confusing stats.

And finally, within seconds, you see the polished answer right in your chat window — ready to use, share, or act on. You don’t have to open multiple tabs or scan pages. Everything just works, quietly and smoothly in the background.

✅ Example Queries:

• Best sushi restaurants in San Francisco
• Current weather in London
• Who won the NBA Finals 2024?

🔧 Pro Tips

• Keep your API keys secure (OpenAI and SerpAPI both)
• Use the Chat node for easy testing before deploying on real platforms
• Stay on the free tier until your needs grow

🧠 Future Scope

Once you’ve mastered this basic setup, the possibilities open up fast — and wide. This foundation isn't just for one small tool; it’s the launchpad for building full-scale AI-powered systems that solve real-world problems.

Here are just a few powerful directions you can take this:

WhatsApp Agents:

Imagine building an AI agent that chats with users on WhatsApp — answering questions, taking orders, sharing updates, or booking appointments, all automatically. Businesses love this because it saves time and keeps customers engaged 24/7.

RAG Agents (Retrieval-Augmented Generation):

Want your AI to answer questions based on your personal data, documents, or knowledge base? RAG agents let you do exactly that. You feed it your own database — and it can fetch relevant info and generate smart, contextual replies like a real expert.

Custom Tools for Global Location-Based Businesses:

Whether it’s a chain of restaurants, logistics providers, or local service companies, you can build tools that work with location data, business listings, and live customer queries. Think: “Show me the top-rated plumbing services near me” — answered in real-time, using up-to-date Google info.

This is just scratching the surface. Once you’ve built one good agent, you’ll start seeing opportunities everywhere — and your skills will be in serious demand.

You can easily sell such agents to small businesses for $150–$300 per project. Once you master it, you can generate $1000–$2000/month or more.

🎯 What’s Next?

In the next blog, we’ll build a RAG Agent that answers based on your own data. Perfect for businesses with internal FAQs or documents.
