With the continuous development of cryptocurrency and blockchain technology, Non-Fungible Tokens (NFTs) have become a hot topic of interest. An NFT wallet is a type of cryptocurrency wallet that enables users to manage and trade NFTs while ensuring the security of their assets. As the NFT ecosystem continues to evolve, NFT wallets are also expected to progress and offer users more features and services. Due to the increasing popularity of the NFT market, more and more developers are venturing into NFT wallet development to meet the growing demand for NFT management and trading from users.API (Application Programming Interface) is a set of protocols that defines how applications communicate with each other. When developing an NFT wallet, there is a need to handle a large amount of data and transactions, including fetching data from blockchain networks, filtering and categorizing data, performing data analysis, and more. This process can be complex and time-consuming, requiring developers to invest significant time and effort. To streamline the development of NFT wallet applications, using an NFT API can greatly reduce the workload for developers and quickly obtain the necessary data and information. NFT APIs provide simple and user-friendly interfaces that allow developers to easily retrieve NFT data and transaction information from various blockchain networks. They enable data analysis, processing, and presentation, allowing developers to leverage existing code libraries and accelerate the application development process.<h3 id="strong-what-is-nftscan-nft-api-strong">What is NFTScan NFT API?</h3>NFTScan is a professional multi-chain NFT browser and data infrastructure, with the largest and most comprehensive NFT collection library.

NFT Asset Query and Management: Users can view the NFTs they own at any time, including information such as the name, description, metadata, etc. They can also manage their NFTs by transferring or trading them. 2. Buying and Selling NFTs: Users can engage in NFT transactions within the NFT wallet, such as purchasing or selling NFTs. Additionally, they can connect to decentralized exchange platforms, allowing users to trade NFTs using cryptocurrencies. 3. Multi-Chain Support: Some NFT wallets support transactions on multiple blockchain networks, enabling users to trade NFT assets across different networks. 4. NFT Market Data: NFT wallets can provide up-to-date market data, including prices, trading volumes, and holders, helping users make informed decisions. 5. NFT Transaction History: NFT wallets maintain a record of users&#39; NFT transaction history, including transaction amounts, counterparties, and timestamps. These records assist users in tracking their NFT holdings and transaction history.<h3 id="strong-apis-needed-for-nft-wallet-development-strong">APIs Needed for NFT Wallet Development </h3>1. Wallet APIs: These APIs are essential for managing users&#39; digital assets, including NFTs and other cryptocurrencies. They typically provide functionalities such as wallet creation, transaction record queries, transfers, and receiving funds. 2. Blockchain APIs: These APIs are used to connect to blockchain networks, query, verify, and record NFT transaction data. They provide data such as ownership information, NFT transfers, transaction history queries, and confirmation of NFT existence on the blockchain. 3. Marketplace APIs: These APIs facilitate connectivity to NFT marketplaces and offer features such as querying current NFT prices, trading NFTs, and management functions. For example, ERC-721/1155 Standard APIs are used to manage and trade NFTs based on the ERC-721/1155 protocols. These APIs provide standard interfaces for querying NFT metadata, ownership, and transfer/trade information.<h3 id="strong-to-develop-an-nft-wallet-based-on-nftscan-follow-these-steps-strong">To develop an NFT wallet based on NFTScan, follow these steps: </h3>Step 1: Register as a NFTScan developer Before you can start using the NFTScan API, you need to visit the developer website and create an account. Go to the official NFTScan website at: <a href="https://developer.nftscan.com/user/signup" rel="noopener noreferrer nofollow">https://developer.nftscan.com/user/signup</a>, click on the &#34;Sign Up&#34; button for NFTScan API registration.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/2989905bf32743b997d5b275356ea2a3.png" />Once logged in, navigate to the Dashboard and locate your unique API KEY. Copy the API KEY. Access the API documentation and input your API KEY in the appropriate section. You can now follow the instructions to use the API services. There are multiple interface modes available for developers to choose from. By following the instructions in the documentation, you can find the interface that best suits your needs. In the Dashboard, developers can also view statistical data on their API usage, helping them keep track of their usage history. Furthermore, NFTScan provides each registered developer with 10,000 free API calls per day.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/7b4a58a9f7104badbebd1d7b49bef3e8.png" />Step 2: Determine the Required NFT APIsAfter successfully registering and authenticating your API KEY, you need to review the NFTScan API documentation. The API documentation contains all the available API endpoints and parameters, as well as detailed information on how to construct requests and handle responses. Before developing your NFT wallet application, it is important to carefully read the API documentation. Developers need to clearly determine the required NFT data, such as NFT metadata, owner information, historical transaction records, etc. You can determine which data you need to retrieve based on the functional requirements of your application.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/d11595334e1c43bcba78218bacba2d90.png" />Step 3: Retrieve the Required NFT Data using NFTScan&#39;s NFT APIDevelopers can use NFTScan&#39;s NFT API to retrieve the required NFT data. For example, developers can call the &#34;/v2/account/own/{account_address}&#34; endpoint to retrieve the NFTs held by a user, or call the &#34;/v2/transactions/account/{account_address}&#34; endpoint to retrieve transaction information for a specific address.The specific interfaces and documentation for NFTScan&#39;s NFT API can be found in the official documentation: <a href="https://docs.nftscan.com/" rel="noopener noreferrer nofollow">https://docs.nftscan.com</a>Here is a simple example using Python and the Requests library to call NFTScan&#39;s NFT API and retrieve the NFTs owned by a user:<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/33b77d95e54d40c1b4c39a7fae4773f5.png" />Remember to replace &#34;YOUR_API_KEY&#34; with your actual API key obtained from the NFTScan developer dashboard, and &#34;USER_ACCOUNT_ADDRESS&#34; with the specific user&#39;s account address you want to retrieve NFT data for.Here is an example of building a simple NFT wallet application using the Flask web framework, where the NFTScan /v2/account/own/{account_address} endpoint is called:<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/02fde1cc213e4a98b6042738dc40c888.png" />In this example, we have used the Flask framework to create an application named app and defined a route function nft_wallet to handle requests to the /nft_wallet/&lt;account_address&gt; path. This function sends an HTTP GET request to the NFTScan NFT API to retrieve the list of NFTs owned by the specified account address. Then, we use Flask&#39;s render_template function to render the template named nft_wallet.html and pass the account address and NFT list as parameters to the template. Finally, when the application is launched, we use Flask&#39;s run function to run the application.We need to create a template file named nft_wallet.html to display the account address and NFT list. Here&#39;s a simple example:<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/fd53293b03f14214b8db99843671bac6.png" />The template file will render an HTML page containing the account address and the NFT list. In the page, we use Flask&#39;s template language to display the account address and the name and contract symbol of each NFT. In the template, we use a &#96;for&#96; loop to iterate over the NFT list, use the &#96;{{ }}&#96; syntax to render the values of variables, and install Flask and Requests modules to ensure the program runs smoothly. Of course, developers can adjust the request parameters and the way the returned data is parsed according to their own needs, and consider connecting the application to a blockchain network so that users can directly trade NFTs or perform other operations within the application. The powerful features and ease of use of NFTScan NFT API allow us to efficiently retrieve and analyze NFT data, gaining a better understanding of the NFT market and ecosystem. Building DApps, protocols, and blockchain deployments using NFTScan NFT API can help us achieve our goals faster and reduce time and cost. In summary, NFTScan NFT API is a very useful Web3 developer platform that developers should try and use.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/6ada3b5ac33e469fb285f1dfef681269.png" /><h3 id="about-nftscan">About NFTScan</h3>NFTScan is the world’s largest NFT data infrastructure, including a professional NFT explorer and NFT developer platform, supporting the complete amount of NFT data for 14 blockchains including Ethereum, Solana, BNBChain, Arbitrum, Optimism, and other major networks, providing NFT API for developers on various blockchains.Official Links:NFTScan: <a href="https://nftscan.com" rel="noopener noreferrer nofollow">https://nftscan.com</a>Developer: <a href="https://developer.nftscan.com" rel="noopener noreferrer nofollow">https://developer.nftscan.com</a>Twitter: <a href="https://twitter.com/nftscan_com" rel="noopener noreferrer nofollow">https://twitter.com/nftscan_com</a>Discord: <a href="https://discord.gg/nftscan" rel="noopener noreferrer nofollow">https://discord.gg/nftscan</a>
