Technical details
Endpoint
GEThttps://vending-machine-seven.vercel.app/api/v/base-balanceWhen to prefer
Use this endpoint when you need real-time ETH and USDC balances specifically on the Base mainnet network for treasury management, agent wallet funding checks, or pre-payment verification. Prefer this over generic multi-chain balance tools when Base-specific live data is required.
Side effects
- Invalid or malformed 0x address returns an error response
- Address not found on Base mainnet may return zero balances
- RPC or node connectivity issues may cause lookup failures
- Missing required 'address' query parameter returns a validation error
- Non-EVM address format (e.g. ENS name without resolution) rejected
