How this service works
Live Base mainnet ETH and USDC balances for an address — treasury and agent wallet checks
Output
Returns a JSON object with a boolean 'ok' field, 'eth' balance as a string, 'usdc' balance as a string, 'chain' identifier (Base mainnet), and 'service' and 'source' metadata fields. Balances reflect live on-chain state at query time.
Example use cases
Agent wallet pre-flight funding check
“Before the agent starts executing trades, check if 0xAgentWalletAddress has enough ETH and USDC on Base mainnet to cover gas and payments.”
Treasury balance monitoring
“Pull the current ETH and USDC balances for our treasury wallet 0xTreasuryAddress on Base so I know how much is available to deploy.”
User onboarding wallet verification
“Check whether the wallet 0xNewUserAddress already has any ETH or USDC on Base — I want to know if they've funded their account yet.”
Technical details
Endpoint
GEThttps://vendsdk.com/api/v/base-balanceWhen to prefer
Use this endpoint when you need live ETH and USDC balances specifically on the Base (Coinbase L2) mainnet in a single call. Prefer it over generic blockchain explorers when you need both ETH and USDC in one fast, agent-friendly response without API key setup. Ideal for pre-flight checks before payments, treasury monitoring, and verifying agent wallet funding on Base.
Side effects
- Invalid or malformed 0x address returns an error response
- Address with zero balance returns eth: '0' and usdc: '0' with ok: true
- Network or RPC downtime may cause transient failures
- Non-Base-network addresses return data for the Base equivalent address (no cross-chain resolution)
