## 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 evm-wallet-balance-summary-7ccaf65a
```

Example prompt: Can you pull up the wallet balance summary for 0x1234...abcd — show me the native token plus USDC, USDT, and WETH balances across Base, Arbitrum, and Optimism?

## When to prefer this

Choose this endpoint when you need a fast, aggregated multi-chain balance snapshot for an EVM wallet covering native tokens and the most common stablecoins/WETH. It is ideal for portfolio checks, treasury audits, or pre-transaction funding verification across Ethereum, Base, Arbitrum, Optimism, and Polygon without needing to query each chain separately. Prefer alternatives if you need full ERC-20 token lists, NFT holdings, historical balances, or tokens beyond the major stablecoins and WETH.

## Known failure modes

- Invalid or malformed 0x wallet address returns an error
- Unsupported chain name in the chains parameter is ignored or returns an error
- Public RPC node timeout or unavailability may cause partial or failed responses
- Rate limiting or payment failure (x402) blocks the request
- Empty balances returned for wallets with no holdings (not an error, just zeros)

## How this service works

EVM wallet summary: native + major stablecoin/WETH balances across 5 chains (public RPC). 0.02 USDC/call on Base.

## Output

Returns a structured breakdown of the wallet's balances including native token (ETH/MATIC etc.), major stablecoins (USDC, USDT), and WETH for each requested chain, fetched directly from public RPC nodes. Data is organized per chain and per token.
