API

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.

Endpoint:

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

  1. 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)

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

  • Get all rented collection NFTs by user wallet

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

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

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;
}
