onchain-wallet-balances: GET /wallet/balances
Native-coin balance + ERC-20 token balances (raw + human) for any address on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base). On Base pass token symbols or 0x addresses (or a default common set); on other networks pass explicit 0x token addresses.
