This overview aims to help developers understand how to retrieve data and make use of it in their projects.Assets API: “Assets” are the most crucial data fields in NFT, used to uniquely identify and describe digital assets. By extracting the “Assets” data from NFTs on the blockchain, developers can gain comprehensive insights and build related applications. The “Assets” object provides a unique identifier for digital assets and data on their entire lifecycle, serving as the foundation for developers to understand and apply NFTs.Transactions API: The transaction model represents the complete transaction data of an NFT asset on the blockchain, providing developers with information on the full lifecycle transactions of NFTs. This includes NFT minting, transfers, sales, and other transaction activities, enabling developers to gain a deeper understanding of the flow and evolution of Ordinals in the Bitcoin ecosystem. NFTScan continuously aggregates NFT transaction market data and related transaction contract information from various blockchain networks, providing valuable insights for tracking and understanding the dynamics of the NFT market. It also helps developers in building NFT-based applications and tools.Collections API: NFTScan gathers off-chain data related to NFT collections, including descriptions, social media, and other basic information. This data is obtained through APIs provided by the most mainstream NFT markets on various blockchain networks. Additionally, floor price information is based on centralized data from NFT market order information, which can also be accessed through APIs.<img src="https://mirror.xyz/_next/image?url&#61;https%3A%2F%2Fimages.mirror-media.xyz%2Fpublication-images%2FyMK92YE4eaBCk1OQvOK7y.png&amp;w&#61;3840&amp;q&#61;75" />1/ Retrieve Assets Series<ul><li>Get NFTs by account (Retrieve NFTs by wallet address)</li><li>Get minted NFTs by account (Retrieve minted NFTs by wallet address)Get NFTs by collection (Retrieve NFTs by collection name and sort by inscription_id in ascending order)</li><li>Get single NFT (Retrieve a single NFT)</li><li>Get NFTs by output (Retrieve NFTs by output)</li><li>Get cursed inscriptions (This endpoint retrieves a set of cursed inscription NFTs, sorted by inscription_number in ascending order)</li></ul>Here we can use the “Get cursed inscriptions” endpoint “/btc/assets/cursed/inscription” to retrieve details of a set of cursed inscription NFTs. Query parameters include cursor, limit, and show_attribute for selection. Some inscriptions that have been successfully engraved do not have an allocated index and therefore cannot be retrieved, hence they are referred to as “cursed inscriptions”. NFTScan also integrates and indexes this data for the convenience of developers.<img src="https://mirror.xyz/_next/image?url&#61;https%3A%2F%2Fimages.mirror-media.xyz%2Fpublication-images%2FY1kqRzgPH6qAb8pj8nm7s.png&amp;w&#61;3840&amp;q&#61;75" />2/ Retrieve Transactions Series<ul><li>Get transactions by account (This API returns a list of NFT transactions for a wallet address)</li><li>Get transactions by inscription ID (This API mainly retrieves BTC NFT transactions by Inscription ID)</li><li>Get transactions by collection (This API returns a list of transactions for a specific collection, sorted in descending order by timestamp)</li><li>Search transactions (This API returns a list of Ordinals transactions applying search filters in the request body)</li></ul>Here, we will use the Get transactions by inscription ID interface with the path: “/btc/transactions/{inscription_id}”, to retrieve transaction records for inscription ID 6fb976ab49dcec017f1e201e84395983204ae1a7c2abf7ced0a85d692e442799i0. The query parameter fields available for selection include event_type (transaction event type): Mint/Transfer, separated by ‘;’ for multiple events.<img src="https://mirror.xyz/_next/image?url&#61;https%3A%2F%2Fimages.mirror-media.xyz%2Fpublication-images%2F0aBANQgLCulsOdrjM63RK.png&amp;w&#61;3840&amp;q&#61;75" />3/ Retrieve Collections SeriesGet an NFT collection (Retrieve details based on Collection name)Search NFT collections (This endpoint returns information about collection lists by applying search filters in the request body.

For example, in Python, you can use the requests library to send a GET request, set the API endpoint and request headers, and configure the request parameters as needed, and finally handle and print the response data.Here, we will use the “Get an NFT collection “//btc/collections/{collection}” to retrieve details of a collection named Bitcoin Frogs. We will make an HTTP GET request to access NFTScan’s API interface. Using Python’s requests library, you can construct the request like this:import requestsSet the API endpoint and Collection namecollection_name &#61; &#34;Bitcoin Frogs&#34; api_url &#61; f&#34;https://api.nftscan.com/v1/btc/collections/{collection_name}&#34;Set the request headersheaders &#61; { &#34;Authorization&#34;: &#34;Bearer YOUR_API_KEY&#34;, # Replace YOUR_API_KEY with your actual API key &#34;Content-Type&#34;: &#34;application/json&#34; }Send the GET requestresponse &#61; requests.get(api_url, headers&#61;headers)Handle the response dataif response.status_code &#61;&#61; 200: data &#61; response.json() print(&#34;API Response Data:&#34;, data) else: print(&#34;Request failed with status code:&#34;, response.status_code)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>
