How to use the API

How can i make requests using the API. I cannot find documentation on how to use the API and what kind of requests i can make only the response i get from the API. I have an API key but i don't know how to use it to make a request.

Is there documentation on how the urls for the different requests are ?

If there is, direct me to it please
