            timeout=15  # Set a 15-second timeout for the request
        )
        response.raise_for_status() # Raise an exception for bad status codes

        data = response.json()["data"]
        markdown_content = data.get("markdown")

        if markdown_content:
            print(f"Successfully extracted Markdown from {url_to_scrape}:")
            print(markdown_content[:500] + "...") # Print first 500 characters
            break # Exit loop on success
        else:
            print(f"No markdown content found for {url_to_scrape}.")
            break # Exit loop if no markdown, even if request was successful

    except requests.exceptions.Timeout:
        print(f"Attempt {attempt + 1}: Request timed out. Retrying...")
        time.sleep(2 ** attempt) # Exponential backoff
    except requests.exceptions.RequestException as e:
        print(f"Attempt {attempt + 1}: An error occurred: {e}. Retrying...")
        time.sleep(2 ** attempt) # Exponential backoff
    except Exception as e:
        print(f"An unexpected error occurred: {e}")
        break # Exit loop on unexpected error
