This is a very basic no-frills scraper to retrieve the metadata and digital assets from all tokens minted on hicetnunc.xyz. I share this as a starting point for people who want to experiment with building alternative views on the works created on the platform or preserve the data. Feel free to improve upon this or add additional features.
