How this service works
Live Base wallet balance for AI agents. Returns native ETH and Circle USDC balances, atomic values, block height, contract address, and observation time for any EVM address. Includes a machine-readable upgrade path to treasury readiness for spend, gas-reserve, and wallet-health decisions. No API key.
Output
A JSON response containing the native ETH balance, Circle USDC balance (both in atomic/wei units and human-readable form), current block height on Base, the USDC contract address used, and the UTC timestamp of the observation.
Example use cases
Pre-payment balance verification
“Before you execute that 50 USDC transfer on Base, check the live ETH and USDC balance for wallet 0xAbCd...1234 so we know there's enough to cover it.”
Autonomous agent treasury check
“My agent needs to top up a contract — first check the current ETH and USDC balances on Base for address 0xDeF0...9876 and tell me the block height and observation time you see.”
DeFi position pre-flight check
“Before the bot tries to execute the swap, look up the live Base balance for 0x9999...aaaa — I need the native ETH amount, the Circle USDC amount in atomic units, and what block it was observed at.”
Technical details
Endpoint
POSThttps://anywaypossible.com/api/base-balanceWhen to prefer
Use this endpoint when an AI agent needs a real-time, pre-transaction balance check on the Base blockchain specifically — especially before autonomous payments or DeFi actions. Prefer this over generic blockchain explorers when you need atomic-unit values, block height context, and observation timestamps in a single structured API response with no API key required.
Side effects
- Invalid or malformed EVM address returns an error response
- Network or RPC node unavailability may cause timeouts or stale data
- Non-Base EVM addresses may return zero balances if queried against the wrong chain
- Payment failure (x402) if the 0.001 USDC fee is not included in the request
