NFTFi is an abbreviation for &#34;NFT&#34; and &#34;Finance,&#34; with the aim of &#34;increasing NFT liquidity and providing cash flow.&#34; NFTFi is an emerging ecosystem that focuses on decentralized protocols and applications designed to enhance the financial utility of NFTs. It utilizes NFTs as the foundational layer to build economic infrastructure.In practice, the NFTFi protocol offers DeFi capabilities for NFTs, including the ability to unlock leasing, lending, and fractionalizing NFTs. It also facilitates the creation of derivatives and prediction markets based on them. This transformation equips NFTs, originally lacking in liquidity, with financial attributes, thereby shaping them into new financial instruments and asset allocation forms. This expansion opens up greater possibilities for the applications of NFTs.In decentralized financial platforms based on NFTs, obtaining comprehensive and reliable NFT data is crucial for implementing various operations such as asset valuation, risk management, and interest calculations.<blockquote>NFTScan NFTFi&#xff1a;https://www.nftscan.com/nftfi</blockquote><img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/8d1f3cab47d4485d92a525685efab49f.png" />It can be said that comprehensive and real-time NFT data support is a vital guarantee for the smooth operation of decentralized financial platforms like NFTFi. Obtaining cross-chain heterogeneous NFT data poses a significant challenge for development teams of platforms like NFTFi. They need to address various issues such as data fragmentation, lack of standardized formats, and real-time updates. Automated and efficient data services can lower the entry barriers and are currently in high demand for development teams.As a pioneer in NFT data services, NFTScan provides professional and reliable solutions to various platforms. Its extensive APIs and cross-chain support undoubtedly contribute to the thriving development of the entire NFT financial ecosystem. NFTScan has built an NFT index database covering 17 major public blockchains. Developers can easily access standardized and visualized NFT data by simply calling NFTScan&#39;s NFT API. The powerful SDK facilitates developers in integrating NFT data services quickly and conveniently, eliminating the need for them to independently obtain and convert heterogeneous assets.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/e8deaa844c674140806114539006b616.png" />How to Access the NFTScan NFT APICreate a NFTScan Developer AccountBefore using the NFTScan API, you need to visit the developer website and create an account.

It sorts holders within the specified collection by their holdings and provides a distribution description of the number of NFTs held and the duration of holdings. This information helps analyze the distribution of holders within a project, assess market concentration, and evaluate asset liquidity. You can refer to NFTScan Holders for reference:<blockquote>https://www.nftscan.com/0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d?module&#61;Holders</blockquote>After entering your API Key and clicking &#34;Try it,&#34; the data returned includes 20 items in total. This data includes wallet addresses of top holders, their holdings&#39; values, and the percentage of holdings they represent, among other distribution data.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/cbe60a32179b45ca975c3bb267c98948.png" />2) Collection Holding Period Distribution/v2/statistics/period/distribution/{contract_address}This API returns data on the distribution of holding periods for NFTs, calculating the percentage of NFTs held within different time intervals. These holding period distribution data can be useful for observing and analyzing the market liquidity and holder structure of an NFT project. It helps assess the investment value and risk associated with a series of NFTs. Therefore, it is very helpful for NFTFi platform asset evaluation and model building. You can refer to NFTScan Holding Period Distribution for reference:<blockquote>https://www.nftscan.com/0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d?module&#61;Holders</blockquote><img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/d7f990db401345ddac37870ee56ca5fd.png" />3) Get Transactions by Contract/v2/transactions/{contract_address}This API allows you to retrieve all historical transaction information related to a specified NFT contract address. It provides comprehensive and reliable query access to contract transaction data, enabling you to obtain information such as the historical transaction prices and transaction flows of NFTs associated with that contract. Transaction details can reconstruct the entire circulation and transaction history of the NFT contract, providing a clear picture of the market activity and trading volume of the NFT project.Clicking &#34;Try it&#34; returns data: You can see that for the contract address 0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d, the data returned includes detailed information for each transaction. This information comprises the block number where the transaction occurred, timestamp, transaction hash, sender address, recipient address, token ID, token quantity, transaction price, and more.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/155a8ccf14564091bf16267ab9b24704.png" />4) Get All Multi-Chain NFTs by Account/v2/assets/chain/{account_address}This API returns detailed data for multi-chain NFTs held by the specified account address. The data includes information about the NFT&#39;s blockchain, contract address, token ID, name, description, image, holding duration, special attributes, and more. NFTs are grouped based on contract addresses. This interface provides an overall view of the account&#39;s multi-chain NFT assets. Developers can use a single API call to retrieve complete details of NFTs on different chains held by the account, eliminating the need to query each chain and contract individually. Here, we are querying the multi-chain NFT data held by the account:0xca1257ade6f4fa6c6834fdc42e030be6c0f5a813 (Whale Address).<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/f4cd6adcbbf8470a97c3358a9181362b.png" />3/ Constructing Relevant NFT API RequestsDeveloping NFT data services using NFTScan&#39;s API is highly convenient and efficient. NFTScan provides developers with comprehensive API documentation and parameter descriptions. Developers can choose the appropriate interface based on their business requirements, configure the necessary request parameters, and quickly call the API using code or tools to obtain rich and accurate NFT data. This eliminates the need for developers to manually extract and convert on-chain data. Compared to the complexities of handling on-chain data, NFTScan automates NFT data collection and standardization, significantly reducing the barrier to access usable NFT data. For example, here we make a request:0xca1257ade6f4fa6c6834fdc42e030be6c0f5a813 for multi-chain NFT details using the endpoint /v2/assets/chain/{account_address}. Below is a simple Python example code:<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/dbe10dfc7f9d441995d9df33b048e2a5.png" />In this example, we first define the API URL by incorporating the address as a path parameter. We then use the requests library to make a GET request to the API, retrieve the response, and finally check the status code. If the request is successful, we print the JSON data from the response. This example demonstrates how to request NFTScan API and obtain multi-chain NFT details for the specified address. Developers can further process and analyze the returned NFT data according to their specific needs.<img src="https://miro.medium.com/v2/resize:fit:1400/0*BLPv3qExcBv5tDjl" /><h2 id="header-0">About NFTScan</h2>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 17 blockchains including Ethereum, Solana, BNBChain, Arbitrum, Optimism, and other major blockchains, providing NFT API for developers on 16 blockchains.Official Links:NFTScan: https://nftscan.com/Developer: https://developer.nftscan.com/Twitter: https://twitter.com/nftscan_comDiscord: https://discord.gg/nftscan
