Example use cases
DeFi portfolio balance check
“Can you check the ETH balance on Optimism for wallet 0xAbCd1234567890AbCd1234567890AbCd12345678? I want to know how much is sitting there before I make a move.”
Verify payment receipt on Optimism
“Did the payment arrive? Check the on-chain balance of 0x1234567890abcdef1234567890abcdef12345678 on Optimism and tell me the current native token amount.”

Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/optimism/balance/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to look up the native token balance of a specific wallet on the Optimism L2 network. Prefer this over Ethereum mainnet balance endpoints when the user explicitly references Optimism or OP Mainnet. Ideal for lightweight, single-address balance checks without needing a full blockchain node.
Side effects
- Invalid or malformed wallet address returns an error
- Address with zero balance may return 0 rather than an error
- Network congestion or RPC issues could cause timeouts
- Non-EVM-compatible address format will fail validation
