How this service works
ERC-20 token balance of a wallet, read live on-chain: send "token,wallet". Default chain Base; prefix another: ethereum:, arbitrum:, optimism:, polygon:, bsc:. $0.01 per call.
Output
Returns the live ERC-20 token balance for the specified wallet and token contract on the requested chain, read directly from on-chain state. Typically includes the raw balance value and possibly token metadata like decimals or formatted amount.
Example use cases
DeFi bot pre-trade balance check
“Before executing this swap, check the live on-chain USDC balance for wallet 0x1234...abcd on Arbitrum so I know if there are enough funds.”
Multi-chain portfolio token audit
“Can you check the WETH balance of wallet 0xDead...Beef on Ethereum mainnet and the same wallet on Polygon so I can compare holdings across chains?”
Airdrop eligibility verification
“I need to verify the on-chain token balance of wallet 0xFeed...C0de for the AIRDROP token at contract 0xToken...1234 on Base — can you look that up live?”

Endpoint
GEThttps://chain.intel.rallylive.ca/chain/erc20-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, live on-chain ERC-20 token balance for a specific wallet across Base, Ethereum, Arbitrum, Optimism, Polygon, or BSC — especially in DeFi automation, pre-trade checks, or airdrop verification workflows where stale cached data is unacceptable.
Side effects
- Invalid token contract address returns error or zero balance
- Invalid or malformed wallet address returns error
- Unsupported chain prefix returns error
- Network congestion or RPC issues may cause timeout
- Zero balance returned if wallet holds none of the specified token
