Description
BlockSpan serves as an NFT API platform tailored for software companies engaged in blockchain development. By consolidating information from various blockchain networks, we offer a streamlined API that enables NFT developers to access real-time data such as token prices, ownership status, and metadata, including pre-cached images. Transitioning between multiple blockchains or utilizing different chains doesn't have to be a cumbersome process; instead of laboriously scraping block logs, you can effortlessly implement a straightforward REST API integration. Our API provides more than just transactional information; it also delivers details on pricing, current ownership, and extensive metadata. Currently, our platform supports Ethereum, Polygon, Arbitrum, and Optimism, with additional blockchain integrations on the horizon. We have also created comprehensive documentation for every endpoint, which features an interactive API console to enhance usability. Moreover, our NFT API is designed to include token metadata and cached image URLs, effectively reducing the need for multiple API and IPFS calls to gather that information. With such functionality, developers can focus on building innovative applications without the hassle of backend complexities.
