## 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 erc-20-token-balance-with-decimals-and-symbol-53536312
```

Example prompt: What's the ERC-20 token balance for wallet address 0xAbC...123 holding USDC (contract 0xA0b...eB4) on Ethereum, including the decimals and symbol?

## When to prefer this

Use this endpoint when you need both the raw ERC-20 token balance AND the token metadata (decimals and symbol) in a single call, saving an extra round-trip compared to fetching balance and metadata separately. Ideal for agents that need to display human-readable token amounts without knowing the token's decimal precision in advance.

## Known failure modes

- Invalid or malformed wallet/contract address returns an error
- Non-ERC-20 contract address may return unexpected or empty data
- Unsupported chain or network not available returns an error
- Rate limiting or payment failure returns a 402 or 429 response
- Node/RPC timeout if the underlying chain is congested
