In the exciting world of Non-Fungible Tokens (NFTs), developers are at the forefront of innovation, creating applications that use the special qualities of these digital assets. Covalent is crucial to this endeavour, offering complete NFT indexing and easy data access with its Unified API. In this article, we will look at how Covalent assists developers in making unique apps that show NFT data in a creative way.

Integrating the Covalent API for Robust NFT Data Solutions

The Covalent API is a treasure trove for developers aiming to create advanced NFT applications. Covalent's diverse endpoints cater to different aspects of NFT development. These endpoints are divided into three categories.

Core Rendering

The core rendering endpoints are built to easily display NFT assets and their metadata. They feature endpoints such as Get NFTs for address, Get trait summary for collection and Get NFT transactions for contract, among others. With these highlighted endpoints, developers can render the NFTs held by an address, calculate rarity scores for a collection based on its traits, and build a transaction history table with all the transactions of an NFT token. All of Covalent’s NFT endpoints support both the ERC-721 and ERC-1155 token standards.

Market Data

The market data endpoints are made for creating charts that show how well an NFT collection is doing. The endpoints consist of historical floor prices, historical trading volume and historical sales count from different time periods. The flat shapes of these responses are great for time-series charts. They make it easier for users to see when and where to invest.

Ownership & Token Gating

Lastly, the ownership and token-gating endpoints focus on verifying what users hold in their wallets. Token-gating is a common digital mechanism in Web3. It controls access to specific content, services, or experiences based on token ownership. Many Discord servers or events are reserved only for token holders. Covalent’s endpoints help developers check if a wallet address has a particular NFT or any NFT in a certain collection, giving them special access.

Why the Covalent API is Ideal for NFT Application Development

Covalent's approach to NFT data is uniquely beneficial for developers:

  1. Speedy and Reliable Data Access: The caching of NFT assets and metadata ensures that applications receive up-to-date and reliable information swiftly. Users can monitor Covalent’s data coverage and NFT caching efforts here.

  2. Unified Data Across Blockchains: Covalent’s structured schema integrates data from multiple blockchains, providing the same request and response format across over 200 indexed chains. This makes development easier by removing the need for multiple tools and messy data, speeding up developers' work.

  3. Optimized Endpoints for Frontend Performance: Covalent’s API endpoints are designed to facilitate easy integration and smooth user experiences in applications. Covalent gives complete data for a specific use case, instead of just snippets like RPCs.

  4. Streamlined Data Gathering: Covalent's comprehensive API addresses all NFT-related data needs, offering streamlined pathways to this data and saving developers time in data collection and processing.

Practical Use Cases for Developers Using The Covalent API

Building Marketplaces

Using the core rendering and market data points, developers can make apps like OpenSea or Rarible. This allows users to easily grasp NFT markets and collections.
