An NFT explorer, a digital tool accessible via websites or apps, enables users to monitor non-fungible tokens (NFTs) ownership, historical records, and valuations. This explorer facilitates the search for specific NFTs, the examination of prevailing market prices, and the tracing of sales and ownership chronicles. Some NFT explorers boast supplementary features, such as watchlist creation, portfolio performance tracking, and NFT price comparison across various marketplaces.A notable characteristic of NFT smart contracts is their exclusion of the artwork, imagery, or files themselves, containing only links or URIs to these elements and their metadata. Consequently, the responsibility for hosting this content does not fall upon the blockchain, as the tokens merely pinpoint off-chain locations for the files and data.NFTScan’s NFT API provides swift access to comprehensive NFT information from multi-chain blockchains, such as EVM chains, Solana, Aptos, and Bitcoin networks.Bypassing the need for manual scanning, indexing, and data storage, users can now issue a single request to obtain specific NFT information for both ERC-721 and ERC-1155 tokens. This encompasses information retrieval, such as identifying all NFTs associated with an address or obtaining metadata and attributes for a specific NFT token.NFTScan SDK ToolThe NFTScan SDK libraries offer seamless deployment of smart contracts and invocation of methods on prevalent contract definitions via the NFTScan API, eliminating the need for developers to master Solidity, compile code, or import ABIs.Employing the SDK, one can effortlessly execute calls on supported networks utilizing JavaScript.Moreover, the SDK delineates standard read and write methods, with read methods accessible for trial through interactive REST APIs.Use GuideStep 1: Access NFTScan Analytics SDK Tool<ol><li>Visit <a href="https://docs.nftscan.com/guides/Overview/1" rel="noopener noreferrer nofollow">NFTScan API Docs</a>, select the SDK option in the menu bar</li></ol><img src="https://miro.medium.com/v2/resize:fit:1400/1*zgbMwbHlizsNmc3zd1Yy3Q.png" /><a href="https://docs.nftscan.com/guides/Overview/1" rel="noopener noreferrer nofollow">NFTScan API Docs</a>2. Click the “JS- SDK” to take you to the NFTScan SDK <a href="https://github.com/nftscan-official/nftscan-api-js-sdk" rel="noopener noreferrer nofollow">GitHub repository</a><img src="https://miro.medium.com/v2/resize:fit:1400/1*5iueIryQeiP1pqHl8Z4wgA.png" /><a href="https://docs.nftscan.com/guides/SDK/2" rel="noopener noreferrer nofollow">JS-SDK</a><img src="https://miro.medium.com/v2/resize:fit:1400/1*pCPzQ82tPBBKOUDrHYExgw.png" /><a href="https://github.com/nftscan-official/nftscan-api-js-sdk" rel="noopener noreferrer nofollow">GitHub repository</a>Step 2: Set Up Your Development EnvironmentBefore you start building your app, you need to set up your development environment. Ensure that you have the following tools installed on your computer:1. <a href="https://nodejs.org/en/download/" rel="noopener noreferrer nofollow">Node.js</a>: This is a JavaScript runtime built on Chrome’s V8 JavaScript engine, which allows you to run JavaScript on the server-side.2. <a href="https://git-scm.com/downloads" rel="noopener noreferrer nofollow">Git</a>: This is a version control system that allows you to manage your code and collaborate with other developers.3. A code editor: Choose a code editor that you are comfortable with. Some popular options include Visual Studio Code, Sublime Text, and Atom.Step 3: Clone the SDK RepositoryOnce your development environment is set up, clone the SDK repository from GitHub. Open your terminal or command prompt and run the following command:<img src="https://miro.medium.com/v2/resize:fit:1400/1*XTTi4LhG8l8ZFyNK9So0Wg.png" />Step 4: Install DependenciesNavigate to the cloned repository’s directory using the terminal or command prompt and run the following command to install the required dependencies:<img src="https://miro.medium.com/v2/resize:fit:1400/1*N-LNFvVv7pqd2kW5yMB-SQ.png" />Step 5: Create Your NFT Explorer AppNow that you have the NFTScan SDK and its dependencies installed, it’s time to create your NFT Explorer app. In this tutorial, we will create a simple command-line app that fetches NFT data from the NFTScan API. You can later expand this app to include a user interface or integrate it with your existing project.1. Create a new file in the nftscan-sdk directory called nft-explorer.js.2. Open the nft-explorer.js file in your code editor and start by importing the necessary modules:<img src="https://miro.medium.com/v2/resize:fit:1400/1*rIMZ0Qr_Ej2E_AfcAvA9qg.png" />3. Initialize the NFTScan instance and set up the API configuration:<img src="https://miro.medium.com/v2/resize:fit:1400/1*Lw95xgLfXT8ZDpR-2IExpA.png" />Replace ‘your_nftscan_api_key’ with your own NFTScan API key. You can obtain an API key by signing up for a free account on the NFTScan website and navigating to the API settings page.4. Create a function to fetch NFT data from the OpenSea API:<img src="https://miro.medium.com/v2/resize:fit:1400/1*uoGHhf09-O1VVzYWnRSH1w.png" />This function takes in the assetContractAddress and tokenId as arguments and fetches the corresponding NFT data from the NFTScan API. The function then logs the NFT’s name, description, image URL, and owner address to the console.5. Create a function to fetch NFT data from the NFTScan API:<img src="https://miro.medium.com/v2/resize:fit:1400/1*F_SPRYQ0pmLeH8aKqD0bNg.png" />Replace the sampleAssetContractAddress and sampleTokenId with the appropriate values for the NFT you want to explore.6. Save the nft-explorer.js file and run the app using the following command in your terminal or command prompt<img src="https://miro.medium.com/v2/resize:fit:1400/1*6s_Z3eOBuiV9p2iOolNlqw.png" />If everything is set up correctly, you should see the NFT data for the specified asset contract address and token ID logged in the console.ConclusionCongratulations! You have successfully built a basic NFT Explorer app using the NFTScan SDK tool on GitHub. This app can be further expanded and customized to suit your needs. You can add more features, such as searching for NFTs by keywords, filtering by various attributes, or even integrating it with a web or mobile app to create a visually appealing user interface.<blockquote>Happy coding!</blockquote><img src="https://miro.medium.com/v2/resize:fit:1400/1*Q6Y2ggVDHzbmXUlTvOV_Pg.png" />About NFTScanNFTScan 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><a href="https://nftscan.medium.com/?source&#61;post_page-----9d4fc39c5871--------------------------------" rel="noopener noreferrer nofollow"> </a>
