How this service works
EVM Wallet Balance: native ETH + USDC balance of any address on Base Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-evm-balance","request":"<input>"}. No account, no API key.
Output
Returns the live ETH (native) balance and USDC token balance for the specified EVM wallet address on the Base network, sourced directly from on-chain consensus state at the time of the call.
Example use cases
Pre-transaction balance check
“Before I send that transfer, can you check the live ETH and USDC balance on Base for wallet 0xAbCd1234...? I want to make sure there are enough funds.”
Portfolio monitoring for a tracked address
“What are the current native ETH and USDC balances on Base for 0xDeAdBeEf...? I'm keeping an eye on this address for my records.”
DeFi bot funding verification
“Check the Base blockchain right now and tell me the ETH and USDC balances for 0x9a8b7c6d... — I need to confirm the bot wallet is funded before it executes.”

Use this endpoint when you need a quick, real-time lookup of both native ETH and USDC balances for a specific wallet on Base, without needing full portfolio details. Prefer it over broader wallet portfolio endpoints when only balance figures are needed, as it is cheaper per call and faster. Ideal for pre-transaction checks, funding verification, and balance monitoring in automated agents.
Side effects
- Invalid or malformed wallet address returns an error response
- Address with no activity on Base may return zero balances
- Network congestion or node unavailability may cause timeouts
- Incorrect serviceId value in request body causes service routing failure
- Payment failure via x402 protocol blocks execution
