🕷️ ScrapeGraphAI: You Only Scrape Once

English | 中文 | 日本語 | 한국어 | Русский

Downloads linting: pylint Pylint CodeQL License: MIT

ScrapeGraphAI is a web scraping python library that uses LLM and direct graph logic to create scraping pipelines for websites and local documents (XML, HTML, JSON, Markdown, etc.).

Just say which information you want to extract and the library will do it for you!

ScrapeGraphAI Hero

🚀 Quick install

The reference page for Scrapegraph-ai is available on the official page of PyPI: pypi.

pip install scrapegraphai

playwright install

Note: it is recommended to install the library in a virtual environment to avoid conflicts with other libraries 🐱

Optional Dependencies Additional dependecies can be added while installing the library:
  • More Language Models: additional language models are installed, such as Fireworks, Groq, Anthropic, Hugging Face, and Nvidia AI Endpoints.

    This group allows you to use additional language models like Fireworks, Groq, Anthropic, Together AI, Hugging Face, and Nvidia AI Endpoints.

    pip install scrapegraphai[other-language-models]
    
  • Semantic Options: this group includes tools for advanced semantic processing, such as Graphviz.

    pip install scrapegraphai[more-semantic-options]
    
  • Browsers Options: this group includes additional browser management tools/services, such as Browserbase.

    pip install scrapegraphai[more-browser-options]
    

💻 Usage

There are multiple standard scraping pipelines that can be used to extract information from a website (or local file).

The most common one is the SmartScraperGraph, which extracts information from a single page given a user prompt and a source URL.

import json
from scrapegraphai.graphs import SmartScraperGraph

# Define the configuration for the scraping pipeline
graph_config = {
    "llm": {
        "api_key": "YOUR_OPENAI_APIKEY",
        "model": "openai/gpt-4o-mini",
    },
    "verbose": True,
    "headless": False,
}

# Create the SmartScraperGraph instance
smart_scraper_graph = SmartScraperGraph(
    prompt="Find some information about what does the company do, the name and a contact email.",
    source="https://scrapegraphai.com/",
    config=graph_config
)

# Run the pipeline
result = smart_scraper_graph.run()
print(json.dumps(result, indent=4))

The output will be a dictionary like the following:

{
    "company": "ScrapeGraphAI",
    "name": "ScrapeGraphAI Extracting content from websites and local documents using LLM",
    "contact_email": "contact@scrapegraphai.com"
}

There are other pipelines that can be used to extract information from multiple pages, generate Python scripts, or even generate audio files.

Pipeline Name Description
SmartScraperGraph Single-page scraper that only needs a user prompt and an input source.
SearchGraph Multi-page scraper that extracts information from the top n search results of a search engine.
SpeechGraph Single-page scraper that extracts information from a website and generates an audio file.
ScriptCreatorGraph Single-page scraper that extracts information from a website and generates a Python script.
SmartScraperMultiGraph Multi-page scraper that extracts information from multiple pages given a single prompt and a list of sources.
ScriptCreatorMultiGraph Multi-page scraper that generates a Python script for extracting information from multiple pages and sources.

For each of these graphs there is the multi version. It allows to make calls of the LLM in parallel.

It is possible to use different LLM through APIs, such as OpenAI, Groq, Azure and Gemini, or local models using Ollama.

Remember to have Ollama installed and download the models using the ollama pull command, if you want to use local models.
