💻 Usage

Case 1: Extracting informations using a local LLM

You can use the SmartScraper class to extract information from a website using a prompt.

The SmartScraper class is a direct graph implementation that uses the most common nodes present in a web scraping pipeline. For more information, please see the documentation.

Case 2: Extracting informations using Openai model

from scrapegraphai.graphs import SmartScraperGraph
OPENAI_API_KEY = "YOUR_API_KEY"

# Define the configuration for the graph
graph_config = {
    "llm": {
        "api_key": OPENAI_API_KEY,
        "model": "gpt-3.5-turbo",
    },
}

# Create the SmartScraperGraph instance
smart_scraper_graph = SmartScraperGraph(
    prompt="List me all the news with their description.",
    file_source="https://perinim.github.io/projects/",  # also accepts a string with the already downloaded HTML code as string format
    config=graph_config
)

result = smart_scraper_graph.run()
print(result)

Case 3: Extracting informations using Gemini

from scrapegraphai.graphs import SmartScraperGraph
GOOGLE_APIKEY = "YOUR_API_KEY"

# Define the configuration for the graph
graph_config = {
    "llm": {
        "api_key": GOOGLE_APIKEY,
        "model": "gemini-pro",
    },
}

# Create the SmartScraperGraph instance
smart_scraper_graph = SmartScraperGraph(
    prompt="List me all the quotes, authors and tags ",
    file_source="http://quotes.toscrape.com",  # also accepts a string with the already downloaded HTML code as string format
    config=graph_config
)

result = smart_scraper_graph.run()
print(result)

The output for alle 3 the cases will be a dictionary with the extracted information, for example:

{
    'titles': [
        'Rotary Pendulum RL'
        ],
    'descriptions': [
        'Open Source project aimed at controlling a real life rotary pendulum using RL algorithms'
        ]
}
