The rapid expansion of the blockchain ecosystem has led to an explosion in non-fungible token (NFT) assets. With countless NFTs spread across multiple blockchain networks, developers face significant challenges in accessing, parsing, and utilizing this data efficiently. Retrieving meaningful information from such a vast and fragmented dataset can be time-consuming and technically complex.
Many developers struggle with aggregating NFT data from different blockchains due to interoperability barriers. Even within a single network, the sheer number of NFT projects and assets makes manual data retrieval impractical. This has created a strong demand for reliable infrastructure that simplifies NFT data access and analysis.
Fortunately, several data service providers now offer specialized solutions to address these challenges. NFT data platforms provide robust APIs that allow developers to seamlessly retrieve, analyze, and integrate NFT information into their applications.
Accessing NFTScan NFT API Services
Creating a Developer Account
To begin using NFTScan API services, you must first create a developer account. Visit the official NFTScan developer portal and complete the registration process. After signing up, you will gain access to a personalized dashboard containing your unique API key.
This API key is essential for authenticating your requests to NFTScan's servers. Copy your key from the dashboard and store it securely. The dashboard also provides valuable usage statistics, helping you monitor your API consumption patterns.
New users receive 1 million compute units (CU) for API requests, which never expire. This generous allocation allows developers to thoroughly test and integrate NFT data into their applications without immediate cost concerns.
Understanding API Documentation
After obtaining your API key, carefully review the NFTScan API documentation. This comprehensive resource details all available endpoints, parameters, request formats, and response structures. Understanding the documentation is crucial for effectively leveraging the API's capabilities.
NFTScan supports an extensive range of blockchain networks, including Ethereum, Solana, BNB Chain, Bitcoin, Polygon, zkSync, Aptos, and several others. The platform offers dedicated interfaces for EVM-compatible chains, Solana, Aptos, and Bitcoin, providing consistent data models across different ecosystems.
The API provides access to ERC-721 and ERC-1155 assets, along with transaction histories, project information, and market statistics. With over 50 public endpoints currently available, developers can access diverse NFT data types to meet various application requirements.
Key NFT Retrieval API Endpoints
Retrieve NFTs by Account
This endpoint allows you to fetch all NFTs associated with a specific wallet address. The response groups NFTs by contract address for better organization. If an account holds more than 2,000 NFTs, the response will be limited, and pagination is required to retrieve all assets.
Get All NFTs by Account
Similar to the previous endpoint but designed specifically for comprehensive retrieval of all NFTs owned by an address. This is particularly useful for applications that need to display a complete portfolio of a user's NFT holdings.
Retrieve Minted NFTs by Account
This interface focuses specifically on NFTs that a particular account has minted themselves. This helps in tracking the creative output or investment patterns of specific addresses.
Fetch NFTs by Contract
This endpoint retrieves all NFTs associated with a specific contract address, sorted by token ID in ascending order. It's ideal for analyzing complete collections or projects.
Retrieve Single NFT
For applications needing detailed information about a specific NFT, this endpoint provides comprehensive data about an individual token, including metadata and ownership history.
Get Multiple NFTs
This batch endpoint allows retrieval of multiple NFTs across different contracts simultaneously, improving efficiency when working with diverse NFT collections.
Search NFTs with Filters
This advanced endpoint enables sophisticated filtering of NFT assets based on multiple criteria. Returns results sorted by nftscan_id in ascending order. Note that when filtering by block number, the range between block_number_start and block_number_end cannot exceed 10,000 blocks.
Retrieve NFTs by Attributes
This specialized interface returns NFTs that possess specific attributes within a collection. Helpful for identifying rare or specific trait combinations within NFT projects.
Get All Multi-Chain NFTs by Account
This powerful endpoint aggregates NFT holdings across all supported blockchains for a given wallet address. It provides a unified view of a user's complete cross-chain NFT portfolio, enabling comprehensive analysis and management.

Practical Implementation Examples
Retrieving All NFTs from a Whale Address
When querying the endpoint "Get all NFTs by account" for address 0xca1257ade6f4fa6c6834fdc42e030be6c0f5a813, the response returns 349 items grouped in sets of 100. The data reveals significant holdings in blue-chip NFT collections:
The address contains 26 Bored Ape Yacht Club tokens (BAYC), with a floor price of 30 ETH at time of query. It also holds 23 Mutant Ape Yacht Club NFTs (MAYC) with a 5.7399 ETH floor price, and 23 Bored Ape Kennel Club tokens (BAKC) at 2.1878 ETH floor price.
This information helps identify investment patterns and preferences of major market participants.
Cross-Chain NFT Retrieval
The "Get all multi-chain NFTs by account" endpoint provides a comprehensive view of a wallet's NFT holdings across different blockchain networks. For the same address examined above, the response shows 349 collections on Ethereum and 2 collections on BNB Chain.
This cross-chain functionality enables developers to create unified NFT management dashboards, analyze investment distribution across ecosystems, and build applications that transcend individual blockchain boundaries.
Collection-Wide NFT Retrieval
The "Get NFTs by contract" endpoint allows developers to retrieve all NFTs within a specific collection. For example, querying the Bored Ape Yacht Club contract returns all 10,000 tokens sorted by ID.
The response includes comprehensive data for each NFT, including ownership history, minting information, metadata storage details, and rarity rankings. This enables detailed collection analysis and application features that require complete project data.
Frequently Asked Questions
What is the main advantage of using NFTScan API over direct blockchain querying?
NFTScan API provides pre-processed, standardized, and aggregated NFT data across multiple blockchains. This saves developers significant time and resources compared to building their own indexing systems and parsing raw blockchain data.
How current is the data provided through NFTScan API?
The platform maintains real-time synchronization with supported blockchains, ensuring that API responses reflect the most current on-chain state. Typical data latency is minimal, usually measured in seconds rather than minutes.
Can I use NFTScan API for commercial applications?
Yes, the API is designed to support both development testing and production applications. The generous free tier allows for substantial usage before requiring upgraded plans for commercial-scale applications.
What types of NFT data are available through the API?
The API provides access to NFT metadata, ownership information, transaction history, rarity rankings, collection statistics, and market data including floor prices and trading volumes.
