NFT analysis pack: owner, metadata, holdings and collection
One call to analyse an NFT: its current owner, its metadata (name, description, image, traits from data:, https or ipfs), how many NFTs of the collection that owner holds, and the collection contract (name, symbol, whether it is an upgradeable proxy). ERC-721 on Base, Ethereum, Arbitrum, Optimism or Polygon. Cheaper than the tools bought one by one. Use before buying, listing or verifying an NFT.
Inputs
| Name | Type | Description |
|---|---|---|
contract (required) | string | 0x ERC-721 collection contract address |
tokenId (required) | string | Token id, a whole number |
chain | string | Network: eth (default), base, arb, op or polygon |
