Step 1: Launch Langflow

After installation, start Langflow: 
langflow run
This will start the Langflow server locally at http://localhost:7860.

​
Step 2: Using Tavily Components

Langflow provides two main Tavily components in the Tools section of the components library:

      • Max Results: Number of results to return
      • Search Depth: “basic” or “advanced”
      • Note: Additional parameters are available in the Controls panel
  2. Tavily Extract API: Extract content from web pages
    • Located under Tools > Tavily Extract API
    • Configuration Options: Select the component and go to “Controls” to access all available settings. Here are some key examples:
      • Extract Depth: “basic” or “advanced”
      • Note: Additional parameters are available in the Controls panel
