Thanks - we aim to have a broader set of chains and testnets, that can all be queried from a single endpoint. We also provide a couple of things that make it easier to deal with media, like cached versions and preview sizes via a CDN. We also pull in active floor prices and collection metadata from multiple marketplaces, even when it's stored off-chain.
We do pass through 3D files when the NFT metadata includes them, but we don't have an explicit search function. This is a great product suggestion though, to do search by media type in general.
Fair question - overall volumes are certainly down from the 2021 highs, but there is growth in certain ecosystems (e.g., Solana). Our view is we expect this space to be cyclical like a lot of emerging technologies, especially as new use cases develop beyond digital art and collectibles.
Thank you. There are a couple of common use cases for ownership history. One is to build up the trail of how high profile NFT collections have changed hands. Another is to understand what certain wallets paid for a certain NFT over time to predict future prices. Or to be able to analyze how holders of different types of NFT collections are connected.
