How this service works
Live Base wallet balance - native ETH plus up to 20 ERC-20 balances (default: major tokens such as USDC, WETH, cbBTC, AERO; or caller-supplied ?tokens=) in one bounded JSON-RPC batch (eth_getBalance + balanceOf).
Output
A JSON object containing the queried wallet address, the native ETH balance (in wei and/or formatted ETH), and an array of ERC-20 token entries each with the token contract address and the wallet's balance — covering up to 20 tokens (defaulting to major Base tokens like USDC, WETH, cbBTC, and AERO if none are specified).
Example use cases
DeFi portfolio snapshot for Base wallet
“Can you pull the full token portfolio for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base — I want to see their ETH balance plus USDC, WETH, and AERO holdings.”
Monitor whale wallet balances on Base
“Check the ETH and top ERC-20 balances for Base address 0xAbCd1234abcd1234abcd1234abcd1234abcd1234 — I'm tracking whether this wallet has moved any of its USDC or cbBTC recently.”
Verify token receipt after on-chain transfer
“Did the transfer go through? Check if 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Base now has a USDC balance, and also show me their current ETH.”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/base/portfolio/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick multi-token balance snapshot for a Base chain wallet in a single call — especially useful for portfolio checks, wallet monitoring, or DeFi agent workflows. Prefer this over raw RPC calls when you want aggregated ETH + ERC-20 balances without managing batched JSON-RPC yourself. Choose this over Ethereum or Solana equivalents specifically for Base (L2) addresses.
Side effects
- Invalid or malformed wallet address returns an error or empty response
- Requesting more than 20 token addresses may be rejected or truncated
- Unknown or non-ERC-20 contract addresses will return zero balance or an error
- Temporary RPC node unavailability may cause a timeout or 5xx response
- Address with no activity may return zero balances for all tokens (valid but potentially confusing)
