Input: JSON body {"serviceId":"aman-evm-balance","request":"<input>"}. No account, no API key.
Output
Returns the native ETH balance and USDC token balance of the queried EVM address as live on-chain values from the Base network, reflecting the current consensus state.

Side effects
- Invalid or malformed EVM address returns an error
- Address with no activity may return zero balances
- Payment failure via x402 (insufficient USDC for the $0.001244 fee) blocks the call
- Network or node unavailability may cause timeouts
- Wrong serviceId value causes routing failure
