Returns the on-chain native token balance (e.g. ETH on Base) for the specified EVM wallet address, reflecting the current state of the Base blockchain at query time.
Example use cases
DeFi portfolio balance check
“Can you look up the on-chain ETH balance for my Base wallet at 0x742d35Cc6634C0532925a3b8D4C9B2f4B6F1e2d3 so I know how much native token I have available?”
Automated wallet monitoring alert
“Check the Base chain balance for address 0xAbCd1234567890EFabcd1234567890EFabcd1234 — I want to know if there are any funds sitting there before I proceed.”
User onboarding balance verification
“Verify whether the Base network wallet 0x9f8e7d6c5b4a3210fedcba9876543210fedcba98 has a non-zero native balance so we can confirm the user has funded their account.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/base/balance/:address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need the native token balance of an EVM-compatible wallet on the Base network (Coinbase's L2). It is ideal for agents building DeFi dashboards, verifying user wallet funding, or monitoring on-chain balances without needing a full blockchain node. Prefer this over generic block explorer scraping when you need a simple, paid, programmatic lookup at low cost ($0.003 per call).
Side effects
- Invalid or malformed wallet address returns an error response
- Address with no transaction history may return zero balance
- Network congestion or RPC node issues may cause delayed or failed lookups
- Non-EVM or non-Base addresses will not return valid data
