## 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 ethereal-goods-co-on-chain-wallet-balance-lookup-1198d746 -d '<json body>'
```

Example prompt: What are the current on-chain ETH, USDC, and ERC-20 token balances for the wallet 0xAbC123...DEF456?

## When to prefer this

Choose this endpoint when you need a quick, live on-chain balance check for an Ethereum wallet covering ETH, USDC, and ERC-20 tokens in a single call. It is ideal for agents that need to verify wallet holdings before a transaction, audit DeFi positions, or check airdrop eligibility without building their own RPC infrastructure. Prefer alternatives if you need historical balance data, multi-chain support beyond EVM, or NFT holdings.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet with no transaction history may return zero balances
- Rate limits or network congestion on the Ethereum RPC may cause timeouts
- Non-Ethereum (e.g. Solana, Bitcoin) addresses will not be recognized
- Payment failure ($0.05 USDC) results in a 402 response before data is returned
