🕷️ ScrapeGraphAI: You Only Scrape Once

English | 中文 | 日本語 | 코리아노 | Русский

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, etc.).

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

🚀 Quick install

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

pip install scrapegraphai

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

💻 Usage

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

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 given a single prompt and a list of sources.

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

Case 1: SmartScraper using Local Models

Remember to have Ollama installed and download the models using the ollama pull command.

from scrapegraphai.graphs import SmartScraperGraph

graph_config = {
    "llm": {
        "model": "ollama/mistral",
        "temperature": 0,
        "format": "json",  # Ollama needs the format to be specified explicitly
        "base_url": "http://localhost:11434",  # set Ollama URL
    },
    "embeddings": {
        "model": "ollama/nomic-embed-text",
        "base_url": "http://localhost:11434",  # set Ollama URL
    },
    "verbose": True,
}

smart_scraper_graph = SmartScraperGraph(
    prompt="List me all the projects with their descriptions",
    # also accepts a string with the already downloaded HTML code
    source="https://perinim.github.io/projects",
    config=graph_config
)

result = smart_scraper_graph.run()
print(result)

The output will be a list of projects with their descriptions like the following:

{'projects': [{'title': 'Rotary Pendulum RL', 'description': 'Open Source project aimed at controlling a real life rotary pendulum using RL algorithms'}, {'title': 'DQN Implementation from scratch', 'description': 'Developed a Deep Q-Network algorithm to train a simple and double pendulum'}, ...]}

Case 2: SearchGraph using Mixed Models

We use Groq for the LLM and Ollama for the embeddings.

from scrapegraphai.graphs import SearchGraph

# Define the configuration for the graph
graph_config = {
    "llm": {
        "model": "groq/gemma-7b-it",
        "api_key": "GROQ_API_KEY",
        "temperature": 0
    },
    "embeddings": {
        "model": "ollama/nomic-embed-text",
        "base_url": "http://localhost:11434",  # set ollama URL arbitrarily
    },
    "max_results": 5,
}

# Create the SearchGraph instance
search_graph = SearchGraph(
    prompt="List me all the traditional recipes from Chioggia",
    config=graph_config
)

# Run the graph
result = search_graph.run()
print(result)

The output will be a list of recipes like the following:

{'recipes': [{'name': 'Sarde in Saòre'}, {'name': 'Bigoli in salsa'}, {'name': 'Seppie in umido'}, {'name': 'Moleche frite'}, {'name': 'Risotto alla pescatora'}, {'name': 'Broeto'}, {'name': 'Bibarasse in Cassopipa'}, {'name': 'Risi e bisi'}, {'name': 'Smegiassa Ciosota'}]}

Case 3: SpeechGraph using OpenAI

You just need to pass the OpenAI API key and the model name.

from scrapegraphai.graphs import SpeechGraph

graph_config = {
    "llm": {
        "api_key": "OPENAI_API_KEY",
        "model": "gpt-3.5-turbo",
    },
    "tts_model": {
        "api_key": "OPENAI_API_KEY",
        "model": "tts-1",
        "voice": "alloy"
    },
    "output_path": "audio_summary.mp3",
}

# ************************************************
# Create the SpeechGraph instance and run it
# ************************************************

speech_graph = SpeechGraph(
    prompt="Make a detailed audio summary of the projects.",
    source="https://perinim.github.io/projects/",
    config=graph_config,
)

result = speech_graph.run()
print(result)

The output will be an audio file with the summary of the projects on the page.
