How to bind gettyimages.com and retrofit (or OkHttp) on android?

Question

Android

Good afternoon!
In my application, I want to fasten the search for images from the gettyimages service, for which I use the Retrofit library .
I registered on the gettyimages site, got all the keys, looked at the examples on github, I'm trying to get an answer - an error (401). I can't figure out what could be the problem. I try on a standard request - "Api-Key:j878g39yx378pa77djthzzpn" " https://api.gettyimages.com/v3/images/452224426 "
Does anyone have a working example of linking retrofit (or OkHttp) and gettyimages?
Thank you!
