Need help with Roblox Web APIs

Hello! I’m trying to use the users.roblox.com/v1/users/search endpoint, (or whatever the user search endpoint is).

I’m pretty new to JavaScript, though when trying to do a simple get request I run into a CORS error, to resolve this I’ve decided to run my own CORs Proxy though now I run into issues of rate-limits and a seemingly slow request speed. I will face rate-limits allowing only 1 search per minute.

I’ve tried looking at other websites such as Rolimons or RoTrade and they use their own API, so how would I go about the search user endpoint?
