Blast is a Layer2 network launched by Blur, or more specifically by Pacman, the founder of Blur. It is a second-layer network based on Optimistic Rollups technology and is compatible with Ethereum, allowing Ethereum developers and dApps to easily connect to it. Users can obtain passive income by cross-chain assets to the Blast network. Blast opens up new business models for the ecosystem of dApps. ETH and stablecoins that are cross-chained to Blast will automatically generate income. DApps can easily monetize their deposits through a single configuration.

According to data from NFTScan, as of March 21, the Blast Network has issued a total of 915,822 NFT assets, with 1,275 NFT Collections, generating 1,644,848 interaction records. There have been 265,950 wallet addresses that have interacted with the network, with a total trading volume of 2,554.23 ETH.

After successfully registering a developer account and obtaining an API Key, you need to review the NFTScan API documentation. The API documentation contains all the available API endpoints and parameters, as well as detailed information on how to construct requests and handle responses. 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 is designed to help developers improve their experience of obtaining NFT data analysis.

NFTScan currently has the largest and most comprehensive NFT Collection library in the entire network. It supports full data of NFTs from Ethereum, Solana, BNBChain, Bitcoin, TON, Polygon, zkSync, Aptos, Linea, Base, Avalanche, Arbitrum, OP Mainnet, Starknet, Scroll, Viction, Fantom, Moonbeam, PlatON, Cronos, and Gnosis, 23 blockchain in total. It covers a wide range of NFT data and provides a set of interfaces to obtain ERC721 and ERC1155 assets, transactions, projects, market statistics, and more. It now supports over 60 public interfaces for EVM-compatible chains, as well as a set of interfaces for Solana, Aptos, Bitcoin, and TON with the same model, which largely meets the needs of developers to index various types of NFT data.

The Blast 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 serve their own Dapp services effectively.

Assets API: “Assets” represent the most crucial data fields within NFTs, uniquely identifying and describing digital assets. By extracting the “Assets” data from the Blast network, developers can gain comprehensive insights and build relevant applications. 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 Blast 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.

1/Retrieve Assets Series

Here we use the Get minted NFTs by account API “/v2/account/mint/{account_address}” to retrieve detailed information about the Minted NFTs under a wallet address. The path parameter includes the account_address for selection, and the query parameter includes the choice of erc721/erc1155 NFT assets. Here we are querying all erc721 NFTs minted under the address 0x87bc2f2ba8c83f412fed5c3151de0ffbdc959984.

2/ Retrieve Transactions Series

Here we use the Get transactions by contract API “/v2/transactions/{contract_address}” to retrieve NFT transaction records for a specific NFT contract address. The query parameter allows you to select the NFT event types for transactions (Mint/Transfer/Sale/Burn) and you can use ‘;’ to separate multiple events.

Similarly, here we are retrieving the NFT transaction records for the BACGenesis. We are filtering by the Mint event type. The response data will contain all the key data of the items minted under this NFT Collection, such as transaction hash, From and To addresses, block information, gas consumption, transaction timestamp, and other characteristic information of NFT transactions.

3/ Retrieve Collections series

Here we use the Get an NFT collection API

“/v2/collections/{contract_address}” to retrieve detailed information about the NFT collection with the address 0xcfc4c2b14af5b1f8ed97e1717b009dca461d8461 and the name BACGenesis.

4/ Collection Statistics: Statistical Analysis for Collection

Here we use the Collection Top Holder API

“/v2/statistics/collection/holder/{contract_address}” to primarily return the distribution of holders for an NFT collection. You can refer to NFTScan Holders for an example:

https://blast.nftscan.com/0x71da4d5805c1f2ecce2a41a9f9e026287f2b1f39?module=Holders.

5/ Account Statistics Series

6/ Analytic Statistics Series

This series of APIs is commonly used to retrieve data analysis and statistics-related information on the NFTScan Blast network, such as Trade Ranking and Mint Amount. Such APIs allow developers or users to query, analyze, and retrieve statistical data related to specific data sets or indicators and can be used for various purposes, including market analysis, trend tracking, investment decision-making, and understanding the nature of specific data.

7/ Refresh Metadata

Interfaces like Refresh Metadata can assist developers or users in submitting backend tasks to refresh metadata. Once reviewed, these tasks will refresh the specified item or the entire contract metadata.

8/ Other

Developers can find the required Fantom API interface and parameters in the NFTScan API documentation. They can then use their chosen programming language, such as Python, Java, JavaScript, etc., to write the API request code.

Here we use the Get an NFT collection API endpoint

“/v2/collections/{contract_address}”

to retrieve details about the BACGenesis project on the Blast blockchain. The address we are querying is

0xcfc4c2b14af5b1f8ed97e1717b009dca461d8461.

To access the NFTScan API using an HTTP GET request in Python with the requests library, you can construct the request like this:

import requests# Set API endpoint and contract addressapi_endpoint = "https://api.nftscan.com/v2/collections/"contract_address = "0xcfc4c2b14af5b1f8ed97e1717b009dca461d8461"# Build the complete API request URLurl = api_endpoint + contract_address# Send HTTP GET requestresponse = requests.get(url)# Check if the request was successfulif response.status_code == 200: # If successful, parse the response data data = response.json() # Handle the response data, further processing or display can be done here print(data)else: # If the request failed, print the error message print("Request failed, status code:", response.status_code)

This code sends an HTTP GET request to the NFTScan API using the requests library to retrieve the details of an NFT Collection for a specific contract address. After receiving the API response, the code checks if the request was successful. If successful, it parses the response data and processes it accordingly.

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 24 blockchains including Ethereum, Solana, BNBChain, Arbitrum, Optimism, and other major networks, providing NFT API for developers on various blockchains.
