## How to call it through Zero

```sh
zero fetch --capability citiview-wallet-snapshot-674c0dfb
```

Example prompt: What's the full token balance snapshot for wallet 0x4838B106FCe9647Bdf1E7877BF73cE8B0BAD5f97 on Base — show me native ETH, USDC, USDT, WETH, and any other nonzero tokens, plus the transaction count?

## When to prefer this

Choose this endpoint when you need a quick, multi-token balance snapshot for a single EVM address on Base or Ethereum without setting up your own RPC or indexer. It is especially useful for DeFi agents, portfolio trackers, compliance checks, or counterparty vetting where you want ETH plus major tokens in one call for $0.003.

## Known failure modes

- Invalid or malformed 0x address returns an error
- Unsupported chain value returns a validation error
- Address with zero balances for all tracked tokens returns empty token list
- Network timeout or RPC unavailability returns a 5xx error
- Payment not fulfilled (x402) causes request to be rejected before processing

## How this service works

Wallet snapshot on Base or Ethereum: native ETH balance, nonzero balances of the major tokens (USDC, USDT, WETH, DAI, cbBTC, WBTC and more), transaction count and contract flag.

## Output

A structured object containing the wallet's native ETH balance, nonzero balances for major tokens (USDC, USDT, WETH, DAI, cbBTC, WBTC, and others), the total transaction count, and a boolean flag indicating whether the address is a smart contract.
