NFT Token IDs are important for businesses interacting with Non-Fungible Tokens. Getting one essentially requires monitoring transactions and filtering the Token ID from that hash or digging through what a wallet holds. is an industry-leading solution that can be set up in minutes & as an NFT API lets you get all the data you need for your NFT applications.

What is an NFT Token ID and Why It's Important

Developers need non fungible token data for their NFT applications. By monitoring transactions for NFT collections, developers can keep track of all the movement of all the NFTs in their system. This can facilitate updating user accounts in your app, debugging issues that may arise, and also provide valuable marketing information. Additionally, the NFT token id can be used to represent the token in on-chain listings.

For example

If a developer identifies that particular NFT collections are being traded frequently, they may want to investigate further to see what the NFT represents and why it is popular. This type of information can help developers understand what NFT tokens people are interested in and create new NFTs that appeal to that audience. In this way, tracking NFT smart contracts can be very valuable for NFT project owners.
Knowing when NFT transactions occur is important, but the way to differentiate of tokens from a single smart contract is by monitoring for the NFT Token ID.

NFT Token IDs Used Practically

As more industries start interacting with blockchains, NFTs will naturally have increased utility. Let's look at a couple of ways they are used today and how they could be used in the near future.

NFTs are Big in Web3 Gaming, Here's Why

NFTs are used in web3 gaming to provide players with a layer of ownership over what they use in a game. This is a revolution that allows for true digital ownership of your in-game assets, representing anything from in-game items to unique characters. This allows players to trade or sell their NFTs on secondary markets.

Real ownership of virtual items

For developers building Web3 games, you need to know the NFT information relevant to each user playing your game. Each NFT will have its own in-game characteristics. If the player has the Legendary Fiery Sword NFT, that has an immutable ID and you need to make sure they have it in their inventory when they sign in. Correlating the Token ID with the NFT owner as a signed-in user is critical. 
NFTs and real estate appear to go hand-in-hand.

NFT Apps for Real Estate

NFTs represent an exciting development in the real estate industry. They allow for the ownership and transfer of property in a secure and transparent way. Smart contracts could have a major impact on how real estate is bought and sold. Nfts also provide a way for people to invest in property without having to deal with traditional brokers or middlemen. This could dramatically reduce the cost of buying and selling property.
An NFT data API can be used to track NFT token transactions for all sorts of NFT apps, including keeping tabs on investments, following market trends, or simply monitoring activity related to a particular NFT token id.

How to Get NFT Token ID From a Transaction

The nft token id can be easily obtained from a transaction manually or with an NFT API. Manual way: Simply navigate to your chain's block explorer and enter the transaction hash into the search bar. This will give you all the information you need about that particular transaction, including the nft token id.
This is a manual process which will be fine as a way to start, or if you just need the token ID of one NFT transaction. However, if you need to automatically monitor NFT transactions, an nft data API will be very helpful.

Monitor NFT transactions for a wallet or given address

As NFTs become increasingly popular, it is important for businesses and investors to track transactions related to these tokens. This can provide valuable insights into consumer behavior and help identify new opportunities in the market. Usually, people use an NFT API.
Watch those whale movements!

Whale Watching with the Mateys

In the Web3.0 ecosystem, it can be very useful to keep an eye on whales (people with a lot of crypto or NFTs) because they may get early information about new projects that will be highly valuable. This is why many people like to monitor whale wallets for NFT transactions.
Etherescan is a good manual option.

The Slow Way

Visit the address of the wallet in your and then click on the "ERC-721" tab and click into each NFT transaction. This is not an ideal solution for people running analytics or automatic processes. An NFT data API that exposes data whenever your target address sends or receives an NFT can also provide the NFT token ID.

Do it with an NFT API

The most efficient way to get information about NFT prices, an NFT Application, or to retrieve details about one given token of a collection is simply to use an NFT API. Some of these are available through marketplaces, NFT projects, and there are multiple services that offer an API. There is that lets you access blockchain data for any NFT Project without a single line of code.

How to get NFT token IDs using hal Streams

All NFTs can be connected to transactions between addresses on the blockchain. This means that if you need to monitor for the NFT token IDs for your ecosystem, it is best to capture this data based on transaction events. Solutions like block explorers are not scalable for most projects, and building your own NFT data API is cost prohibitive.
The easiest way to filter and query blockchain data.

Introducing hal Streams for your NFT Needs

hal offers powerful developer tools for anyone who needs to capture NFT data. Using hal Streams, developers can monitor individual smart contracts and expose data from a single API endpoint. Hal Streams can be set up in minutes with no-code. Hal Streams supports powerful filtering logic so you can start monitoring and getting NFT API data based on the conditions you care about most. All you need to start is a free account and an API key that you can generate later.

You want to get all the token IDs that are minted from your smart contract

To set up your NFT API, log into and Create a Blueprint. Select Contract Events.
Select the type of trigger you want.
Then, enter the contract address of your NFT smart contract. In this case, we'll use CryptoPunks.
Enter the contract address.
Now that you've added the contract address, hit Continue. Now you have the option to filter smart contract event data. We want to monitor all Transfer events.
Filter blockchain data by event.
Finally, give it a name. Then Save and Deploy.

More Ways hal Streams Can Be Used for NFT Token IDs

Hal Streams is Web3's easiest and most versatile blockchain API.
It's easy to listen to a smart contract using hal Streams and your free API Key. Let's look at two ways you can use this tool.

Filter NFT Transactions by Wallet

If you only care about the (for example) CryptoPunks transactions from a particular whale, then all you have to do is add this as a filter to your hal Streams Blueprint. All you have to do is add the filters "To" and "From" and insert the wallet address to our no-code UI.

Stream NFT Data to Your Web3 Game Backend

Most Web3.0 games are built on hybrid tech-stacks that combine blockchain for asset ownership and centralized backends to actually run the game for users. When a user signs into your game with their Metamask wallet, it's required that your game's backend instantly recognize the NFT Token ID(s) they own so you can associate that to the NFT Metadata and give them access to their inventory.

Supports Historical Queries

Using hal Streams, not only can you monitor transactions in real-time to update your users inventory if they trade NFT items in the game, but you can also query historical data on that user's wallet address to get a comprehensive stream of NFT API data. This obviates the need for custom-coded listening, can be set up in minutes, and lets you focus on building your game.

NFT Data API Options

NFT data APIs are essential for anyone working with blockchain-based tokens. These APIs provide developers with a simple way to access information about NFTs, including metadata, ownership, and transfer history. This information is essential for verifying ownership and preventing the misrepresentation of token holders. Additionally, NFT data APIs make it easy for developers to build applications that use NFTs. Remember to store your API key.
There are many solutions out there. The problem is that most are extremely expensive and take a lot of time to set up.
