OpenAI API Response Documentation

I’m building an OpenAI client, but in the OpenAI API reference, there is no Documentation about the shape/data types of the responses that the endpoints return. There are only examples, but they do not cover all possible outputs. I found some community libraries that have well-documented the response shape/data types. If there is any Documentation about this, please share it. I posted in the OpenAPI Discord, and I have no answer yet.
