# User NFTs

The Asset Manager API provides functionalities for managing asset managers in a blockchain-based ecosystem. Asset managers are entities responsible for managing various assets, such as digital tokens, NFTs (Non-Fungible Tokens), and other digital assets, on a blockchain network. These APIs allows users to retrieve information about asset managers based on their chain ID and contract address.

## **1. Use StreamNFT Indexer (1 API Call to get all User NFTs)**

{% openapi src="/files/JDvLeszlVCuXftU6TcEv" path="/getNFTs/{chainId}/{wallet}" method="get" %}
[openapi: 3.yml](https://2149345960-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F60fGWUP51b2HhkWIrtTW%2Fuploads%2FWP8VXOGi3kSHdwa6ls9J%2Fopenapi%3A%203.yml?alt=media\&token=ecf4e985-c4d9-4317-8a12-07f905e89c2f)
{% endopenapi %}

## **2. Use External Indexer (2 API Call to get all User NFTs)**

*Query Parameters specific for rentals***:**

* `collection`: Filter for token address of the NFT collection
* `rentee`: Filter for assets rented by a wallet
* `state`: Filter for all assets on Marketplace (STALE) or rented out (RENT)
* `onlyRentData` : Output only rental data (NFT rentee, NFT owner,  rental expiry, state)

{% openapi src="/files/YWXbKkMC1LmJdKtNi8qq" path="/assetManager/{chainId}" method="get" %}
[openapi.yml](https://2149345960-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F60fGWUP51b2HhkWIrtTW%2Fuploads%2F487GZkzQet3aXAmxAbT0%2Fopenapi.yml?alt=media\&token=41d5ce99-7329-4bd4-bcfd-32dccbd1fb77)
{% endopenapi %}

**Response:**

* Successful responses return an array of asset managers for provided token address with detailed information, such as the current rentee and the state of each asset.

### Example: How to Integrate **External Indexer**

* Get all rented collection NFTs by user wallet

```javascript
let nfts= indexerCall(wallet.address) // indexer call to get nfts by wallet
nfts.push.apply(nfts, await getNFTs(chainId,wallet.address,tokenAddress));

async function getNFTs(chainId, address,tokenAddress){
    const nfts = await fetch(`https://indexer.streamnft.tech/assetManager/${chainId}?user=${walletAddress}&collection=${collectionAddress}`)
    .then(response => {
        if (!response.ok) {
        throw new Error(`HTTP error! Status: ${response.status}`);
        }
        return response.json();
    })
    .catch(error => {
        // Handle network errors or API response errors here
        console.error('Error:', error.message);
    });
    return nfts;
}
```

* Get all rented NFTs by user wallet

```javascript
let nfts= indexerCall(wallet.address) // indexer call to get nfts by wallet

async function getNFTs(chainId, address){
    const nfts = await fetch(`https://indexer.streamnft.tech/assetManager/${chainId}?user=${walletAddress}`)
    .then(response => {
        if (!response.ok) {
        throw new Error(`HTTP error! Status: ${response.status}`);
        }
        return response.json();
    })
    .catch(error => {
        // Handle network errors or API response errors here
        console.error('Error:', error.message);
    });
    return nfts;
}
```
