GPT 3 api with Android project

Hi, can anyone guild me about integrating GPT 3 API with my android project? Do I have to use Retrofit for GET and POST ?

No, It’s a project for kids that led them write code easily, with this app they can make small games, drawings, etc, so I want to apply the gpt3 API key to my project that led the young ones to make quizzes, write essays, etc.
