## 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 api2ls-com-evm-token-balance-lookup-dc08d158
```

Example prompt: What's the current USDC balance (contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) for the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum?

## When to prefer this

Use this endpoint when you need a real-time, on-chain balance for a specific wallet on a supported EVM network (Base, Ethereum, Optimism, Arbitrum, Polygon), especially when you want both the human-readable and raw balance along with decimal metadata. Prefer this over exchange APIs when you need trustless, on-chain data rather than custodial account balances.

## Known failure modes

- Invalid or malformed address returns an error response
- Unsupported chain name returns an error
- Invalid ERC-20 contract address causes a failed lookup
- Network or RPC downtime may result in a timeout or error
- Missing required address parameter returns a validation error

## How this service works

Get the live native or ERC-20 token balance of an address

## Output

Returns a JSON object with success flag, the formatted balance string, raw balance (balanceRaw), decimal precision, chain name, queried address, and a timestamp (asOf) indicating when the balance was fetched.
