If the firmware upgrade fails or the miner IP cannot be accessed in the backend on the browser after entering it, what could be the reason and how should I proceed?

What language is API written in and are there any recommended languages?

Does it support customization when users want to achieve functions through APIs that our existing APIs cannot achieve?

Does API have any unique features compared to WhatsMinerTool?

Is there a difference in efficiency and effect between WhatsMinerTool and API when implementing the same function?
