Hive’s NFT Search API is a cloud-based solution designed to identify both exact and modified copies of NFT images by comparing a query image against a comprehensive, real-time index of NFT assets from major blockchains such as Ethereum and Polygon. The API leverages a deep learning image similarity model, optimized for digital art and NFT-specific variations, to detect not only direct duplicates but also images altered through manual or algorithmic changes. For each match, the API returns actionable results, including similarity scores, links to matching NFT images, and detailed token metadata (such as contract address, token ID, and descriptive traits). The service is built for high-volume, real-time use, supporting integration into NFT marketplaces and content platforms to automate fraud detection, copyright enforcement, and asset authentication. Integration is straightforward, requiring only a single API call, and the backend is continuously updated to index new NFT assets as they are minted.
