# Collections

## Create Collection

Launch an NFT collection on Solana mainnet. We currently support two types:

* **Static passes:** All NFTs in a static pass collection have the same image.
* **Numbered passes:** Like static passes, numbered passes all share the same image, but NFTs are distinguishable by a number at the bottom of the image. NFTs are minted in order, where the first NFT minted says "#1" at the bottom.

After calling this endpoint, Comet will automatically start deploying the collection on Solana mainnet. This usually takes 30-60 seconds. To monitor the progress of the deployment, use the `GET /collection` endpoint below.

Note: This endpoint requires an image upload, so the request should be in the form of `multipart/form-data`.
