url = 'https://openai.com/api/pricing/'
crawler = WebCrawler()
crawler.warmup()

result = crawler.run(
    url=url,
    extraction_strategy=LLMExtractionStrategy(
        provider="openai/gpt-4",
        api_token=os.getenv('OPENAI_API_KEY'),
        instruction="Extract all model names and their fees for input and output tokens."
    ),
)

print(result.extracted_content)

Execute JS, Filter Data with CSS Selector, and Clustering

from crawl4ai import WebCrawler
from crawl4ai.chunking_strategy import CosineStrategy

js_code = ["const loadMoreButton = Array.from(document.querySelectorAll('button')).find(button => button.textContent.includes('Load More')); loadMoreButton && loadMoreButton.click();"]

crawler = WebCrawler()
crawler.warmup()

result = crawler.run(
    url="https://www.nbcnews.com/business",
    js=js_code,
    css_selector="p",
    extraction_strategy=CosineStrategy(semantic_filter="technology")
)

print(result.extracted_content)
