How this service works
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.
Output
Returns the native coin balance (e.g. ETH, MATIC, BNB) plus a list of ERC-20 token balances for the queried wallet, each with a raw big-integer amount and a human-readable decimal amount. On Base, optional USD value estimates are also available. Results cover whatever token symbols or 0x contract addresses were requested, or a default common set on Base.
Example use cases
Example prompt
“What are the native coin and token balances for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — include USDC, WETH, and DAI?”
Technical details
Endpoint
GEThttps://webtools402.176-109-107-191.sslip.io/wallet/balancesWhen to prefer
Use this endpoint when you need on-chain token and native coin balances for a specific wallet address across major EVM networks. It is especially useful on Base where you can pass token symbols directly instead of contract addresses, and optionally get USD values. Prefer this over general blockchain explorers when you need programmatic, structured balance data without scraping.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported network value returns a validation error
- On non-Base networks, passing token symbols instead of 0x addresses fails
- Exceeding 25 tokens in the request may be rejected
- Token contract address not deployed on the specified network returns empty or zero balance
- Network RPC unavailability causes a timeout or 503 error
