How’s the correct way to create an NFT that points to something dynamic?

Question

I’m working on a platform that will use ETH to create a collection of NFTs that points to a dynamic function on a server.

Let’s say that we want to point out NFTs to something like a Snapchat filter. It’s an URL because all the different filters will have an specific URI but I don’t know if that’s the correct way to point that specific filter. URI could change at any time.

Maybe I’m thinking wrong about creating NFTs based on those filters?

Thanks!
