Additionally, NFTScan provides 1M CU of API call service to all registered developers for requesting all NFT API interfaces, and the CU never expires until it is used up!Check Mint NFT API DocsAfter successfully registering a developer account and obtaining your API Key, you will need to access the NFTScan API documentation. The API documentation contains all available API endpoints and parameters, as well as detailed information on how to construct requests and handle responses. Please read the API documentation carefully and ensure that you understand how to use the API to retrieve the data you need. The NFTScan API service aims to help developers improve their experience in accessing NFT data analysis.Currently, NFTScan has the largest and most comprehensive NFT Collection library across 20&#43; blockchains including Ethereum, Solana, BNBChain, Bitcoin, TON, Polygon, zkSync, Aptos, Linea, Base, Avalanche, Arbitrum, OP Mainnet, Starknet, Scroll, Blast, Viction, Fantom, Mantle and more. It covers a wide range of NFT data, providing a complete set of interfaces to obtain ERC721 and ERC1155 assets, as well as transaction, project, and market statistics. It now supports over 60 public interfaces for EVM-compatible chains and a batch of similar model interfaces for Solana, Aptos, Bitcoin, and TON, greatly satisfying developers’ needs to index various types of NFT data.<img src="https://miro.medium.com/v2/resize:fit:1400/0*5LcB7PnVV1_HzPok" />Mint NFT API ModelsThe Mint NFT API includes three main models, providing developers with detailed information and descriptions of the core fields within these models. This enables developers to retrieve data and utilize the information to effectively serve their Dapp services.Assets API: “Assets” represent the most crucial data fields within NFTs, uniquely identifying and describing digital assets. Developers can gain comprehensive insights and build relevant applications by extracting the “Assets” data from the Mint Blockchain. The “Assets” object provides the unique identification of digital assets, along with data about their entire lifecycle, laying the foundation for developers to understand and leverage NFTs.Transactions API: The transactions model represents the complete history of all transactions related to an NFT asset on the blockchain, offering developers insights into the full lifecycle of NFT transactions. This includes minting, transfers, sales, and other transaction activities, allowing developers to gain an in-depth understanding of the flow and evolution of NFT assets within the Mint ecosystem. NFTScan continuously aggregates NFT transaction data from various blockchain networks, facilitating developers in tracking and understanding the dynamics of the NFT market. This data also assists developers in building NFT-based applications and tools.Collections API: The Collections API provides NFTScan with off-chain data related to NFT collections, including descriptions, social media information, and other basic details. NFTScan retrieves this information through APIs provided by leading NFT markets across different blockchain networks. Additionally, the current floor price information is based on centralized data obtained through API from NFT market orders and is available for developers to access.<img src="https://miro.medium.com/v2/resize:fit:1400/0*y30XuIC1cHZ6zyKZ" />Mint NFT API Retrieval1/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.

Developers just need to browse the API documentation to find the desired endpoints, and understand the endpoint URL, request method, parameters, etc. Then, based on their requirements, they can choose a programming language such as JavaScript, Python, Java, etc. and use the HTTP request library of that language to send the constructed requests to the endpoint URL. When writing the code, developers just need to organize the API parameters, such as contract address, API Key, etc., and call the corresponding NFTScan endpoint to retrieve standardized JSON data easily.Here, we use the API endpoint “Get an NFT collection”/v2/collections/{contract_address} to fetch details data of the GreenID project on MintBlockchain with the contract address 0x776fcec07e65dc03e35a9585f9194b8a9082cddb. We can make an HTTP GET request to NFTScan’s API endpoint using Python’s requests library like this:import requestsdef get_nft_collection_details(contract_address, api_key): base_url &#61; &#34;https://api.nftscan.com/v2/collections/&#34; url &#61; f&#34;{base_url}{contract_address}&#34; headers &#61; { &#34;Content-Type&#34;: &#34;application/json&#34;, &#34;x-api-key&#34;: api_key }response &#61; requests.get(url, headers&#61;headers)if response.status_code &#61;&#61; 200: return response.json()else: return {&#34;error&#34;: f&#34;Failed to retrieve data: {response.status_code}&#34;}Example usagecontract_address &#61; &#34;0x776fcec07e65dc03e35a9585f9194b8a9082cddb&#34; api_key &#61; &#34;your_api_key_here&#34;nft_details &#61; get_nft_collection_details(contract_address, api_key) print(nft_details)Code Interpretation:Import requests library: Use import requests to import the required library.Define function get_nft_collection_details:contract_address: NFT contract address.api_key: API Key for authentication.Build URL: Concatenate the base URL with the contract_address.Set request headers: Including Content-Type and x-api-key, the latter is used for authentication.Send request: Use requests. get to send a GET request.Handle response:<ul><li>If the request is successful (status code 200), return JSON data.</li><li>Otherwise, retrieve an error message.</li></ul>This code is just an example, developers should refer to the actual application for construction. Make sure to replace your_api_key_here with the actual API Key.<img src="https://miro.medium.com/v2/resize:fit:1400/0*rNlBU_YWot5MZKJT.png" />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 20&#43; 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://medium.com/nftscan/nftscan-launches-nftscan-connect-program-to-support-early-stage-web3-startups-1a0470698002" rel="noopener noreferrer nofollow">Join the NFTScan Connect Program</a>
