Starting with the API : possibilities of the API - is my project idea viable (feasibility)

Hello friends, I am thinking of starting to work with the API and have already posted a question on the sticky posts where related as to which API would be required for my needs.
I saw one project that made use of it and was interested at that moment to start communicating with the club members. My use of the API would be to help visualize data in a different way. being a programmer (2000-2003 canadian pre-uni degree) and a statistician by nature, gotta get some stats I crave and the API seems the way to go for ease of access. Before starting the study of how everything works in these forums (lots of great info present) I must know if it's a viable project based on feasibility.
Question being now for thes current post :
My project is not much more "complicated" that this, (displaying data based on the user, but from DIAMOND MEMBERSHIP deep analysis data), 

https://chessheat.com/?hue=213&user=throughtonsheiralexhebert&year=2023

would I be able to use the basic public API or do I need the authorization one?

Being that for my use I'd require the diamond user statistics, and public users wanting to see their stats could see those public as I would not make a system where the public could enter their username login. This is not that kind of project.
Public frontend : check by username akin to that chess-heat example,
but intranet I'd like to get my deeper personal data to talk about the progression and ''career'' in my Chess.com blogs. Each would be separate, encapsulated project. I'd get data to analyze in one, intranet then only keep the resulting graphs/details. Use them in blogs on here. The public application if possible would show user's data by name entered.
Telling the story of our passion for chess can be helped by those deep stats and there is a youtube channel that inspired me to execute my vision of such data presentation. The chess.com API project would be a first step.

I'm not sure what you mean by diamond membership deep analysis but you can use the regular API to fetch the information you need to perform custom stats. I did something similar on my website: https://www.chessti.me/
