Instructions
[blockchain_data] /v4/data/owners/address 50 credit per API call > 📘 Note for v3 API users: > > As part of our documentation consolidation, we removed the dedicated page for GET /v3/data/owners/address. Users can refer to GET /v4/data/owners/address for the latest documentation, as both endpoints function the same—simply replace v4 with v3 in the API URL if using the v3 version. Check if wallet address owns any specified token (ERC-20, ERC-721 or ERC-1155) on the following blockchains: Ethereum - ethereum-mainnet / ethereum-sepolia / ethereum-holesky Base - base-mainnet / base-sepolia Arbitrum - arb-one-mainnet / arb-testnet BNB (Binance) Smart Chain - bsc-mainnet / bsc-testnet Polygon - polygon-mainnet Optimism - optimism-mainnet / optimism-testnet Celo - celo-mainnet / celo-testnet Chiliz - chiliz-mainnet To get started: Provide a chain name, wallet address and address of any fungible token, NFT or multitoken collection. Our API will return true if provided wallet address owns them. If wallet address does not own the specific token, response body is false and status code is 200. It is also possible to check if wallet address owns a specific NFT by specifying a tokenId.
