FAQ
Use the Zerion API endpoint: /wallets/address/positions/ and provide the Ink address (with chain parameter set to Ink). The API will return token balances, ERC-20 holdings, stablecoins, LP-tokens, etc., held by that address on Ink.
Use Zerion API with this endpoint: /wallets/address/nft-positions/ It will return a list of NFTs owned by the address on the Ink chain, including metadata like token ID, contract address, etc.
Yes, when querying with Zerion API, you’ll need to specify the correct chain/network parameter (corresponding to Ink). This ensures the API executes queries against the Ink chain (not Ethereum mainnet or another L2). Or you can leave the parameter empty and the endpoint will return data for all chains.
