PlatON is a next-generation global computing architecture developed by Wanxiang Blockchain and Matrix Elements. It is revolutionary in its use of the meta-computing framework Monad and the isomorphic multi-chain architecture based on the Reload overlay network. The platform’s vision is to be the first operational service network that delivers complete privacy protection. It offers computing, storage, and communication services, as well as various basic resources such as computing power, algorithms, and data. Additionally, it provides public infrastructure software development, consulting, and operational services.Based on NFTScan data, as of January 5th, the PlatON network has issued 2,710,774 NFT assets and has 2,261 NFT collections. The platform has generated 6,865,324 interaction records, involving 1,180,646 wallet addresses, and a total transaction volume of 190,295.2 LAT.<blockquote>PlatON NFTScan&#xff1a;<a href="https://platon.nftscan.com/" rel="noopener noreferrer nofollow">https://platon.nftscan.com/</a></blockquote><img src="https://miro.medium.com/v2/resize:fit:1400/1*ZYm6TqrVKJ5gsHO4uckfvA.png" /><h3 id="accessing-the-nftscan-nft">Accessing the NFTScan NFT</h3>Step 1: Create a NFTScan Developer AccountBefore utilizing the NFTScan API, visit the NFTScan developer platform and create an account. Go to the official NFTScan website and click on the “Sign Up” button under NFTScan API.<blockquote>NFTScan Developer: <a href="https://developer.nftscan.com/user/signup" rel="noopener noreferrer nofollow">https://developer.nftscan.com/user/signup</a></blockquote><img src="https://miro.medium.com/v2/resize:fit:1400/0*MFoitlY_If4deOoN.png" />Once logged in, find your unique API KEY on the Dashboard. Visit the API documentation and input your API KEY in the designated location. Follow the documentation’s instructions to start using the API services. In the API documentation, developers can find multiple interface modes to choose from based on their requirements.<img src="https://miro.medium.com/v2/resize:fit:1400/0*WEeVMevDs8Ma_n5K.png" />Developers can monitor their API usage statistics in the Dashboard, which helps in keeping track of historical data. Furthermore, NFTScan offers each registered developer 1M CU of API calls, which can be used for requesting all NFT API interfaces, and these CU never expire.Step 2: View PlatON API DocumentationAfter successfully registering a developer account and obtaining an API Key, you need to review the NFTScan API documentation. The API documentation contains all available API endpoints and parameters, as well as detailed information on how to build requests and handle responses. Please read the API documentation carefully and make sure you understand how to use the API to obtain the data you need.NFTScan is currently the platform with the largest and most comprehensive NFT Collection library across various blockchains. It supports complete NFT data from 21 blockchains, including Ethereum, Solana, BNBChain, Bitcoin, TON, Polygon, zkSync, Aptos, Linea, Base, Avalanche, Arbitrum, OP Mainnet, Starknet, Scroll, Viction, Fantom, Moonbeam, PlatON, Cronos, and Gnosis. The platform offers a wide range of NFT data, covering various types of assets, and provides a comprehensive set of APIs to access information on ERC721 and ERC1155 assets, transactions, projects, market statistics, and more. Currently, it supports over 60 public interfaces for EVM-compatible chains and also provides a series of interfaces for Solana, Aptos, Bitcoin, and TON. This extensive support caters to the diverse needs of developers seeking to index different types of NFT data.<img src="https://miro.medium.com/v2/resize:fit:1400/0*T-tdPe-QsRiMyJ3s" /><h3 id="strong-platon-strong-nft-api-model">PlatON NFT API Model</h3>This comprises three primary model interfaces, each with an overview and explanation of core API fields to assist developers in accessing and utilizing data for their Dapp services under development.Assets API: “Assets” represent the most critical data fields within NFT, uniquely identifying and describing digital assets. Developers can extract “Assets” data from NFTs on the PlatON to gain comprehensive insights and construct relevant applications. The “Assets” object provides a unique identification for digital assets and data about their entire lifecycle, serving as a foundation for developers to understand and utilize NFTs.Transactions API: The transaction model represents the complete transaction data for an NFT asset on the blockchain, offering developers a full view of an NFT’s transaction history. This includes NFT minting, transfers, sales, and other transaction activities, providing developers with an opportunity to deeply understand the flow and evolution of NFT assets within the PlatON ecosystem. NFTScan continuously aggregates the NFT transaction market and related contract information from various blockchain networks. Currently, NFTScan has compiled data for tracking and understanding NFT market dynamics, aiding developers in building NFT-based applications and tools.Collections API: NFTScan retrieves off-chain data related to NFT Collections, including descriptions, social media, and other fundamental information. This data is obtained from the most popular NFT markets provided through various blockchain networks. Additionally, floor price information is centralized data derived from order information on NFT markets, and it can be accessed via API.<img src="https://miro.medium.com/v2/resize:fit:1400/0*2nfWZ7Nmm_0vkJKj" /><h3 id="platon-nft-api-retrieval">PlatON NFT API Retrieval</h3>1/ Retrieve Assets Series<ul><li>Get NFTs by account (Retrieve NFTs using a wallet address)</li><li>Get all NFTs by account (Retrieve all NFTs associated with a wallet address and group them by contract address.
