How this service works
Live Ethereum wallet balance - native ETH plus up to 20 ERC-20 balances (default: major tokens such as USDC, WETH, USDT, WBTC, stETH; or caller-supplied ?tokens=) in one bounded JSON-RPC batch (eth_getBalance + balanceOf).
Output
Returns a JSON object containing the queried wallet address, its native ETH balance (in wei and ETH), and an array of ERC-20 token balances, each including the token contract address and raw/decimal balance. Default tokens are USDC, WETH, USDT, WBTC, and stETH unless a custom token list is supplied.
Example use cases
DeFi wallet portfolio audit
“Can you pull the full portfolio for Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to see its native ETH balance plus all the major ERC-20 tokens like USDC, WETH, USDT, WBTC, and stETH?”
Custom token holdings check
“For Ethereum wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B, check how much it holds of these specific tokens: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599, and 0xdAC17F958D2ee523a2206206994597C13D831ec7.”
Whale wallet balance monitoring
“I'm tracking a known whale — address 0x47ac0Fb4F2D84898e4D9E7b4DaB3C24507a6D503. Can you get their current ETH balance and how much USDC, WETH, USDT, WBTC, and stETH they're holding right now?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/eth/portfolio/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a combined native ETH and ERC-20 multi-token balance snapshot for an Ethereum address in a single efficient call. Prefer it over individual token balance lookups when you need a portfolio overview covering major tokens (USDC, WETH, USDT, WBTC, stETH) or a custom set of up to 20 ERC-20s simultaneously. It is ideal for DeFi portfolio auditing, whale tracking, and on-chain balance verification without requiring an API key for major providers.
Side effects
- Invalid or malformed Ethereum address returns an error response
- Token contract address not a valid ERC-20 results in zero or error balance
- More than 20 tokens requested may be rejected or truncated
- Underlying Ethereum node unavailability causes RPC timeout or 503
- Rate limiting or payment failure (402) if x402 micropayment not fulfilled
