This tool retrieves metadata for a given NFT smart contract. Essential for obtaining basic NFT collection details such as contract name, symbol, total supply, token type (ERC721 vs ERC1155), contract deployer address, deployed block number, OpenSea metadata, and contract verification status.
Get Nft Sales
This tool will retrieve NFT sales data across various marketplaces. It allows users to query historical NFT sales data with filtering options such as fromBlock, toBlock, order, marketplace, and limit in order to track NFT sales activity, analyze historical data, monitor specific collections, and get real-time updates on NFT transactions.
Get Nfts For Contract
This tool retrieves all NFTs for a given contract address. It is designed to return a complete list of NFTs from a specific NFT collection by accepting parameters such as contractAddress (required), withMetadata (optional), pageSize (optional), and pageKey (optional). The tool is useful for analyzing collections, building NFT marketplaces, and creating collection analytics.
Get Nft Owners
This tool retrieves the owner(s) for a specific NFT token, supporting both ERC721 and ERC1155 tokens on Ethereum and several Layer 2 chains such as Polygon, Arbitrum, Optimism, and Base. It requires the contract address and tokenId, and returns a list of owner addresses along with an optional pagination key for further results.
Get Token Balances
