Alchemy

Tool to fetch NFTs owned by multiple wallet addresses across different blockchain networks. Returns comprehensive NFT metadata including contract details, images, attributes, and ownership information. Use when you need to retrieve NFT portfolio data for wallets across multiple chains.

This tool retrieves ERC20 token balances for a specified Ethereum address. It can either return balances for all tokens an address has ever interacted with or for a specific set of token contract addresses. It is useful for checking token balances for wallets, monitoring ERC20 token holdings, portfolio tracking, and DeFi applications.

Tool to get token balances for wallet addresses across multiple networks using Alchemy's Portfolio API. Use when you need lightweight balance checks for one or more addresses without full token metadata. Supports up to 3 address/network pairs per request with pagination for large result sets.

Retrieves metadata for an ERC-20 token on Ethereum mainnet, including its name, symbol, decimals, and logo URL. This information is essential for displaying token details in user interfaces, calculating token amounts (using decimals), and showing token branding. Use this when you need to: - Display token information to users (name, symbol, logo) - Convert token amounts between human-readable and contract formats (requires decimals) - Build token listings or portfolio displays - Validate or enrich token data Note: Returns empty/null values for invalid or non-token contract addresses.

Retrieves current token prices by contract address and network from decentralized exchanges (DEXes). Use when you need real-time token price data for specific contract addresses across multiple networks. Price data is aggregated from DEXes only (not CEXes) and weighted by total volume. Supports up to 25 addresses per request across maximum 3 different networks. Returns price in USD by default with timestamp. Response succeeds even if some prices are unavailable.

Tool to get current token prices by symbol (e.g., ETH, USDC, BTC) using aggregated CEX and DEX data. Use when you need real-time cryptocurrency prices in USD or other currencies. Supports up to 25 symbols per request. Note: Response succeeds even if some tokens are missing - check the error field in each result item.

Tool to fetch fungible tokens (native, ERC-20, SPL) for multiple wallet addresses across networks. Returns comprehensive token information including balances, metadata (name, symbol, decimals, logo), and current prices. Use when you need complete token portfolio data for wallets across multiple chains (Ethereum, Polygon, Arbitrum, Base, Optimism, Solana, and 30+ EVM chains). Supports up to 2 addresses with 5 networks each per request, with pagination for large result sets.

Tool to get transaction history for wallet addresses across multiple networks using Alchemy's Data API. Use when you need to retrieve historical transactions with detailed metadata including logs and internal transactions. Supports pagination for large result sets with a maximum of 50 transactions per request.

Tool to check if a wallet address owns any token from a specific NFT collection. Use this when you need to verify collection ownership without retrieving full NFT details, supporting both ERC721 and ERC1155 standards.

Tool to check if a specific NFT token is marked as an airdrop. Use when you need to determine whether an NFT was distributed via airdrop mechanism. Returns true if the token is identified as an airdrop, false otherwise.

Tool to determine whether an NFT was airdropped to the owner address. Use when you need to identify if a specific token was received as an airdrop rather than through a purchase or mint.

Tool to check if a wallet address holds any NFTs from a specific contract. Use when you need to verify NFT ownership for access control, membership verification, or token-gating features. Supports both ERC721 and ERC1155 contracts.

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.

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.

Tool to retrieve metadata for multiple NFT contracts in a single batch request. Use when you need to fetch contract information for several NFT collections at once to improve efficiency and reduce API calls.

Tool to get all NFT contracts owned by an address with contract metadata. Use when you need to retrieve a comprehensive list of NFT collections held by a specific wallet address, including detailed contract information such as token type, total supply, deployer info, spam classification, and OpenSea metadata. Supports pagination for addresses with large NFT holdings.

Tool to retrieve all owners for a specific NFT using Alchemy's v3 API. For ERC-721 tokens returns single owner, for ERC-1155 tokens returns all owners with quantities. Use when you need to identify current ownership of an NFT token.

Retrieves all NFTs in a collection using OpenSea collection slug or contract address. Use when you need to fetch NFTs by collection name rather than contract address. Similar to getNFTsForContract but uses collection slug for easier querying. Supports pagination for large collections.

Retrieves all NFTs for a given NFT contract address. Supports both ERC721 and ERC1155 token standards. Returns detailed NFT data including token IDs, metadata, images, and attributes. Use this to analyze NFT collections, build marketplace features, track collection holdings, or create analytics dashboards. Supports pagination to handle large collections efficiently (returns up to 100 NFTs per request).

Tool to get all NFTs currently owned by a given address. Supports ERC721 and ERC1155 tokens on Ethereum and L2s including Polygon, Arbitrum, Optimism, Base. Use when you need to retrieve NFT holdings for an address with optional metadata.

Tool to retrieve all owner addresses for a given NFT collection contract. Use when you need to analyze NFT ownership distribution, find all holders of a collection, or build ownership analytics for ERC721 and ERC1155 contracts. Optionally returns token balances per owner.

Tool to get all owners of NFTs in a contract with optional token balances. Use when you need to analyze NFT holder distribution, prepare airdrops, or identify token owners for specific collections.

This tool retrieves the number of transactions sent from a specific address (also known as the nonce). It uses the eth_getTransactionCount endpoint to return the transaction count for an address at a specified block tag (latest, pending, earliest, or a HEX block number), which is essential for determining the nonce for subsequent transactions.

Tool to search for keywords across metadata of all ERC-721 and ERC-1155 smart contracts. Use when you need to find NFT collections by name, symbol, or description keywords. Returns contract addresses, names, symbols, token types, deployer info, and OpenSea metadata for matching collections.

Retrieves a comprehensive summary of all attributes and traits for NFTs in a collection, including trait counts and distribution statistics. Use this to analyze rarity, understand collection composition, or build trait filters for NFT marketplaces and analytics dashboards.
