How this service works
Bulk wallet balances on Ethereum, Base, Arc or BNB Chain: up to 50 wallets in one call, the native coin or one ERC20 you name, all read at the same block through Multicall3. Pass ?addresses=0x..,0x..&token=&chain=. Cheaper than 50 single calls, and every row is from one consistent block.
Output
Returns a list of wallet addresses each paired with their balance (native coin or specified ERC20), all sourced from the same block via Multicall3, ensuring consistency across the entire result set.
Example use cases
Portfolio snapshot across many wallets
“I have a list of 30 wallet addresses and I want to see everyone's ETH balance on Base all at the same block — can you pull that in one go?”
DAO treasury multi-wallet audit
“Can you check the USDC token balance (0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) across these 45 DAO-controlled addresses on Ethereum so I can see who's holding what?”
Airdrop eligibility balance check
“Before we do the airdrop, can you verify the native BNB balances for all 50 recipient wallets on BNB Chain so we know none of them are empty?”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/evm-balances-bulk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to read balances for multiple wallets (2–50) in a single consistent call. It is far more efficient and cheaper than issuing individual balance queries per address, and the Multicall3 guarantee means all balances are from the same block — essential for snapshot accuracy, airdrop checks, or portfolio reporting.
Side effects
- More than 50 addresses supplied — request will be rejected or truncated
- Invalid address format (non-0x hex) causes validation failure
- Unsupported chain name returns an error
- Invalid ERC20 token contract address (non-existent or wrong chain) may return zero balances or error
- Network congestion on the target chain may cause timeouts
