Accessing private server information with a link/share code to the server

Hi all, I own a roleplay group for a game on ROBLOX and we have our own Discord bot. I am wondering if theres any API I can access fetch information about a private server? We have the invite code/share URL. We will use this information to display how full our server is. If this is in the wrong category, apologies! Not sure where to put this, thanks. (We don’t own the game that we are making a roleplay group for)
