Automate Research with Tavily API & n8n for Smart Data Extraction

What This Automation Does

This workflow takes a topic you type in a chat window and finds good web search results for it.

It keeps only results that have a high score above 80% to make sure they are reliable.

Then it gets detailed content from the top result’s web page.

Next, it makes a short summary of that page using OpenAI’s chat model.

The final output is a clear and short research summary that you can read quickly or use in reports.

Inputs, Processing Steps, and Output

Inputs

• User search topic: The text you enter in the chat window to start a search.


• Tavily API Key: Needed to access the search and extract services.


• OpenAI API Key: Needed to generate the content summary.

Processing Steps

• The workflow receives your topic from the chat message in the Provide search topic via Chat window node.


• It sends a POST request to Tavily Search API with the topic and options to get web results.


• It filters the results to keep only ones with score above 80% using the Filter > 90% node.


• Selects the top filtered result for deep content extraction.


• Calls Tavily Extract API to get the full content of that web page.


• Passes the extracted content to OpenAI Chat Model to create a concise summary in Markdown format.

Output

The workflow outputs a neat, easy-to-read summary ready for use in reports or quick reference.

Beginner Step-by-Step: How to Use This Workflow in n8n

1. Importing the Workflow

1. Download the workflow file using the Download button on this page.


2. Open your n8n editor where you want to use this workflow.


3. Click Import from File and select the downloaded workflow file.

2. Setting Up Credentials and Configurations

1. Find the node named Tavily API Key and enter your own Tavily API Key.


2. Locate the node that uses OpenAI (usually the Summarize Web Page Content node) and enter your OpenAI API Key.


3. If there are any nodes with IDs, emails, or channels used to send outputs, update them to the correct values you want for your setup.


4. Check the Provide search topic via Chat window node webhook URL and be sure to use it correctly to enter your search topics.

3. Testing and Activating

1. Run the workflow once with a test search term to confirm everything is working as expected.


2. If the test is successful, activate the workflow in the n8n UI to run it live.

Now the workflow will receive your dynamic search input, do the searches, filter and extract content, summarize, and produce results automatically.
