How to Build an AI Agent That Scrapes Google in Real-Time Using N8N + SerpAPI
Earlier, people used to build teams with many people to get work done. But today’s world has become so advanced that this won’t work anymore — now, for all big tasks, people will start building AI agents instead.
If you want to learn AI automation, this is the best starting point. In this guide, I’ll show you how to build a simple agent that scrapes real-time data from Google and gives you a clean answer. You can even sell this to clients later.
💡 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?
- You type a message like “What’s the weather today in Tokyo?”
- SerpAPI fetches real-time Google data
- OpenAI processes it and writes a clean reply
- You see the result in chat
✅ 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
Based on this setup, you can build:
- WhatsApp Agents
- RAG Agents (using your own database)
- Custom tools for Global Address-based businesses
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.
