It is useful for retrieving all NFTs associated with a particular contract, such as when you want to display or analyze all tokens from a given NFT collection contract. For example, you can use it to fetch all NFTs minted under a specific contract on Ethereum or Polygon.

Use Case Examples

  1. Fetch all NFTs from a contract address on Ethereum to display in a marketplace.
  2. Retrieve NFTs from a contract on Polygon for portfolio analysis.
