Token API

Get wallet token balances across chains

Returns the total native + ERC-20 balance of a wallet across one or more supported EVM chains, with USD valuations computed by Ankr's pricing service. Each asset includes contract address, decimals, raw integer balance, and a normalized human-readable balance.

Pass walletAddress (hex address, or ENS name on Ethereum). Scope to specific chains with the blockchain array, or omit it to query all supported chains. Filter by onlyWhitelisted: true (default) to limit results to tokens indexed on CoinGecko, or set to false for the full ERC-20 inventory the wallet has touched.

Pagination via pageSize + pageToken. The endpoint is part of the Token API product (700 compute units per call, $0.00007 at base rate).
