# Collections

On this page, we'll dive into the different Collection endpoints you can use to manage Collections programmatically. We'll look at how to query and create Collections.

Collections represents a group of related NFTs. A Collection is itself an NFT. For example, a Collection can be a group of NFTs where each NFT is a membership pass. 

## The Collection Model
