Obtaining complete and accurate NFT collection data is crucial for developers. It not only provides comprehensive insights and supports various innovative applications but also presents the overall development trends of the collection through detailed data. Additionally, rich historical data can be analyzed to assess its value growth and future potential.

Comparing transaction and activity data over different time periods not only helps identify trading opportunities but also provides valuable insights into segmenting user groups for precise marketing efforts, especially when it comes to NFT Collection holder information. Furthermore, comprehensive data supports visual presentations, enriching application content and enhancing user experiences.

Leveraging a powerful NFT API, developers can model and forecast based on massive data sets, enabling the formulation of intelligent investment strategies. It can be said that obtaining complete and accurate NFT Collection data holds significant value for developers researching the NFT market, making data-driven decisions, and developing innovative applications.

Looking at Ethereum NFTScan data, there are currently a total of 259,229 NFT contracts, 146,341,468 NFT assets, 252,387,389 on-chain NFT records, and 9,828,744 interacting wallet addresses on the Ethereum network.

Currently, developers face various challenges when trying to obtain NFT Collection data, including decentralization, incompleteness, and difficulty in identification. Manual data collection is expensive and cannot meet the demands for large-scale data required for product development, making data retrieval a significant challenge for developers. With an abundance of on-chain assets across different blockchains, relying solely on contract addresses is insufficient for effective differentiation. These factors make it difficult for developers to quickly locate the desired Collection and obtain accurate information.

Through the rich filtering options provided by the NFTScan NFT API, developers can combine multiple dimensions such as different blockchains, contract addresses, wallet addresses, and more to precisely filter data. This assists developers in accurately pinpointing their target NFT Collection and retrieving the complete dataset for that project. In contrast to scattered searching, the NFTScan API enables developers to obtain standardized and comprehensive data with a single request, significantly enhancing development efficiency.

Developers can rapidly access the Collection data they need without the need to individually parse information from various sources or manually fetch contract data. The entire retrieval process is straightforward and efficient, saving both time and development effort. It can be said that the NFTScan NFT API's advanced filtering capabilities make it easy and seamless for developers to obtain Collection data, effectively supporting the development of NFT applications or data analysis.

**Build relevant NFT requests**
Building NFTScan-related NFT data requests is straightforward and convenient. Developers only need to locate the desired API in the comprehensive API documentation, configure the necessary request parameters according to the API specifications, and quickly initiate requests using code or tools like Postman, following the documentation examples. This allows you to access rich NFT data without the need for cumbersome on-chain extraction and data integration.

For example, here's a request for Bored Ape Yacht Club (BAYC):
We are requesting distribution data details for Collection Top Holders under this project address: 0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d. Below is an example Python code snippet:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7ounjb95vw097fkc4ul9.png)

In this example, we use the Python requests library to send a GET request and retrieve distribution details for the Top Holders of an NFT Collection. Please ensure that you have the requests library installed to further process the response data as needed, such as extracting and analyzing holder information and NFT distribution.
NFTScan provides a unified abstraction of on-chain data and offers comprehensive response format documentation. Developers do not need to concern themselves with the underlying implementation details, significantly lowering the barrier to accessing NFT data and simplifying the process of building NFT applications efficiently.
