Alchemy is a blockchain development platform that provides powerful APIs and developer tools for building and scaling Ethereum applications
Tools
Compute Nft Rarity
Tool to compute the rarity of a specific NFT based on its traits and their prevalence in the collection. Use when you need to determine how rare or common an NFT is compared to other tokens in the same collection. Returns a list of traits with their prevalence values (0.0 to 1.0, where lower values indicate rarer traits).
Compute Nft Rarity
Tool to compute the rarity of each attribute for a specific NFT based on its collection. Returns prevalence data for each trait, indicating how common or rare each attribute is compared to other NFTs in the same collection. Use when analyzing NFT rarity for trading decisions, collection analysis, or valuation purposes.
Get Nft Collection Metadata
Tool to get metadata for an NFT collection using its marketplace slug (OpenSea, LooksRare, etc). Use when you need collection-level information such as name, description, social links, and floor price. This is useful for discovering collection details without needing the contract address.
Get Collections For Owner
Tool to retrieve all NFT collections held by a specified owner address. Use when you need to get a comprehensive view of what NFT collections a wallet owns, including collection metadata, ownership counts, and spam classification. Only supported on Ethereum. Supports pagination for large collections and filtering options to include or exclude spam/airdrops.
Get Nft Contract Metadata
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 Contract Metadata Batch V2
Tool to retrieve comprehensive metadata for multiple NFT smart contracts in a single batch request using Alchemy's NFT API v2. Use when you need NFT collection details for multiple contracts efficiently, including contract name, symbol, total supply, token type (ERC721/ERC1155), deployer address, deployment block, and OpenSea marketplace data. Maximum of 100 contract addresses per batch.
