  ```python
  def extract_data(url):
      import requests
      r = requests.get(url=url)
      data = r.json()
      return data['status'], data['sub_title'], data['max_clients']
  
  assert extract_data("https://www.example.com/page1") == ('status_value', 'sub_title_value', 'max_clients_value')
  assert extract_data("https://www.example.com/page2") == ('status_value2', 'sub_title_value2', 'max_clients_value2')
output: def extract_data(url):
      import requests
      r = requests.get(url=url)
      data = r.json()
      return data['status'], data['sub_title'], data['max_clients']
