This guide will help you build an AI-powered system that scrapes data from a website, processes it with AI, and allows users to ask questions based on the extracted information

What You'll Build

A simple API that scrapes data from a website, processes it with AI, and enables users to ask questions based on the extracted information. When users input a query, the system retrieves relevant data from the scraped content and generates accurate, AI-driven responses, ensuring efficient and insightful information retrieval.

Getting Started

1. Project Setup

  1. Sign up at Lamatic.ai (opens in a new tab) and log in.
  2. Navigate to the Projects and click New Project or select your desired project.
  3. You'll see different sections like Flows, Context, and Connections flow.png

2. Creating a New Flow

  1. Navigate to Flows, select New Flow.
  2. Click Create from scratch as starting point. Flow selection

3. Setting Up Your API

  1. Click "Choose a Trigger"
  2. Select "API Request" under the interface options Flow API
  3. Configure your API:
    • Add your Input Schema
    • Set url as parameter in input schema
    • Set response type to "Real-time" Flow API Schema
    • Click on save

4. Scraping the data using Firecrawl

  1. Click the Scraper node Flow Deploy
  2. Select the credentials
  3. Add url as parameter

5. Adding AI Text Generation

  1. Click the + icon to add a new node

  2. Choose "Text LLM" Node Text Gen

  3. Configure the AI model:

    • Select your "Open AI" credentials
    • Choose "gpt-4o-mini" as your Model
  4. Under prompts section click the + icon to add prompt

9. What's Next?

  • Experiment with different prompts
  • Try other AI models
  • Add more processing steps to your flow
  • Integrate the API into your applications

10. Tips

  • Save your tests for reuse across different scenarios
  • Use consistent JSON structures for better maintainability
