# Get Active Listings of a Collection

To query active listings of a collection, we will need to check all listing accounts and see if the listed NFT/cNFT belongs to a pre-defined collection mint list. First thing is to have a mint list of the collection you are interested in. For the sake of this example we will use a DAS call to fetch it.

{% hint style="info" %}
You can also use our [<mark style="color:red;">MintList</mark>](https://airdrop.shyft.to/) tool to get a collection's mint list.
{% endhint %}

For Tensor cNFT, we will be checking for <mark style="color:yellow;">assetId</mark> field. For Tensor Swap program we will be using <mark style="color:yellow;">nftMint</mark> field.

The key is to use GraphQL <mark style="color:yellow;">\_in</mark> filter which checks if the NFT address is present in the mint list.
