Alternative to using creations/get-assets API

I want to get a list of Classic Shirts, Pants, and Gamepasses that a group owns/created, and it appears there’s an api at called creations/get-assets.
Is there any alternatives to this via API? I don’t want to use a Proxy

You can’t use any Roblox API in a game without a proxy so you’ll just have to use one

Wouldn’t I have to provide my .ROBLOSECURITY to an api so it’s using my account to access it?

No. Custom proxies run on a web server that fetches Roblox’s API requests and forwards the result to the roblox script, as far as I know.
