Example Use Cases

Arguably the most interesting parts of the NFT such as image URL and attributes/traits are stored on the metadata. The NFT metadata endpoint can be used to either bulk fetch multiple NFTs' metadata or a single one. Some example use cases:

• NFT Photo Gallery

• Rarity calculator/analysis

• Dynamic/evolving NFTs
