How this service works
Native ETH balance of any Base address (wei + ETH, latest block) via eth_getBalance.
Output
Returns a JSON object containing the queried Base address, its native ETH balance expressed as a wei string (full integer precision), and the same balance converted to ETH as a decimal string, all reflecting the latest block on Base mainnet.
Example use cases
DeFi bot pre-flight balance check
“Before executing the swap, check whether 0x742d35Cc6634C0532925a3b844Bc454e4438f44e has enough ETH on Base to cover gas — show me the balance in both wei and ETH.”
Portfolio dashboard ETH balance
“Pull the native ETH balance on Base for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 so I can display it on the portfolio page.”
Wallet funding verification
“I just funded a new Base wallet at 0x1234567890abcdef1234567890abcdef12345678 — can you confirm the ETH balance has shown up yet?”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/base/balance/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the native ETH balance of a specific Base chain address quickly and cheaply ($0.001 per call). Prefer it over Ethereum mainnet balance endpoints when the user's address is on Base (chain ID 8453). Choose it over broader multi-token balance endpoints when you only need the native ETH balance and want minimal latency and cost.
Side effects
- Invalid or malformed address (non-0x-prefixed or wrong length) returns an error
- Address with zero balance returns wei: '0' and eth: '0.0' — not an error
- Network or RPC timeout may return a 5xx error
- Rate limiting or payment failure (x402) blocks the request
