ScrapeGraphAI - A Revolutionary AI-Powered Web Scraping Library

Project Overview

ScrapeGraphAI is an innovative Python web scraping library that revolutionarily combines Large Language Models (LLMs) and direct graph logic to create intelligent web scraping pipelines. The library can handle websites and local documents (XML, HTML, JSON, Markdown, etc.), and users only need to describe the information they want to extract, and the library will automatically complete the scraping work.

Core Features

        "model_tokens": 8192
    },
    "verbose": True,
    "headless": False,
}

# Create scraper instance
smart_scraper_graph = SmartScraperGraph(
    prompt="Extract useful information from the webpage, including company description, founders, and social media links",
    source="https://scrapegraphai.com/",
    config=graph_config
)

# Execute scraping
result = smart_scraper_graph.run()

OpenAI Model Configuration

graph_config = {
    "llm": {
        "api_key": "YOUR_OPENAI_API_KEY",
        "model": "openai/gpt-4o-mini",
    },
    "verbose": True,
    "headless": False,
}
