ScrapeGraphAI is a *web scraping* python library that uses LLM and direct graph logic to create scraping pipelines for websites, documents and XML files.
Just say which information you want to extract and the library will do it for you!

Follow the procedure on the following link to setup your OpenAI API key: [link](https://scrapegraph-ai.readthedocs.io/en/latest/index.html).

## 📖 Documentation

The documentation for ScrapeGraphAI can be found [here](https://scrapegraph-ai.readthedocs.io/en/latest/).

Check out also the docusaurus [documentation](https://scrapegraph-doc.onrender.com/).

## 💻 Usage
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](https://scrapegraph-ai.readthedocs.io/en/latest/).
### Case 1: Extracting information using Ollama
Remember to download the model on Ollama separately!
```python
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
    }
}

smart_scraper_graph = SmartScraperGraph(
    prompt="List me all the articles",
    # 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)

```

### Case 2: Extracting information using Docker

Note: before using the local model remember to create the docker container!
```text
    docker-compose up -d
    docker exec -it ollama ollama pull stablelm-zephyr
```
You can use which models avaiable on Ollama or your own model instead of stablelm-zephyr
```python
from scrapegraphai.graphs import SmartScraperGraph

graph_config = {
    "llm": {
        "model": "ollama/mistral",
        "temperature": 0,
        "format": "json",  # Ollama needs the format to be specified explicitly
        # "model_tokens": 2000, # set context length arbitrarily
    },
}

smart_scraper_graph = SmartScraperGraph(
    prompt="List me all the articles",
    # 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)
```


### Case 3: Extracting information using Openai model
```python
from scrapegraphai.graphs import SmartScraperGraph
OPENAI_API_KEY = "YOUR_API_KEY"

graph_config = {
    "llm": {
        "api_key": OPENAI_API_KEY,
        "model": "gpt-3.5-turbo",
    },
}

smart_scraper_graph = SmartScraperGraph(
    prompt="List me all the articles",
    # 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)
```

### Case 4: Extracting information using Gemini 
```python
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 articles",
    source="https://perinim.github.io/projects",
    config=graph_config
)

result = smart_scraper_graph.run()
print(result)
```

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

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