# 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.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.shyft.to/solana-indexers/case-studies/tensor/get-active-listings-of-a-collection.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
