## 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 manylives-me-erc-20-token-balance-lookup-af53bab3
```

Example prompt: What's the USDC balance on the Base network for wallet 0xAbC1234567890abcdef1234567890abcdef123456? Give me the raw units and the formatted amount.

## When to prefer this

Use this endpoint when you need to check the ERC-20 token balance of a specific wallet on the Base network, especially for USDC or other stablecoins, and you need both the raw on-chain value and the human-readable formatted amount in a single call. Prefer this over native ETH balance endpoints when querying token contracts specifically.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Invalid token contract address returns an error or unexpected data
- Token contract does not exist on Base network may return zero or error
- Network congestion or RPC issues may cause timeout
- Missing required wallet query parameter returns validation error

## How this service works

ERC-20 token balance of any Base network wallet (the main US-dollar stablecoin by default): raw units, decimals, symbol and formatted amount.

## Output

Returns a JSON object with the wallet address, token contract address, token symbol, raw balance in smallest units, number of decimals, and the human-readable formatted balance (e.g. '1.2345' USDC).
