            format="markdown",
            render_js=True,
            fresh=False  # Use caching for cost efficiency
        )
        
        if result.markdown:
            # Cost-effective analysis with DeepSeek
            response = deepseek_client.chat.completions.create(
                model="deepseek-chat",
                messages=[{
