Can i use custom GPTs with my own build apps ?? is APIs available for that kindly share me articals?

Hi and welcome to the community!
A custom GPT cannot be accessed via API. You can only access them via the ChatGPT interface.
However a custom GPT can connect to another API.
If you want to integrate a GPT model into your app then you can consider building an assistant or using the completions API as @merefield suggests.
