## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability amanchain-evm-wallet-balance-c1c9ef71 -d '<json body>'
```

Example prompt: What are the current ETH and USDC balances on Base for wallet address 0x1234abcd...? I need the live on-chain figures right now.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
