## 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 live-multi-token-wallet-balance-native-erc-20-unykorn-genesis402-96fadfb1 -d '<json body>'
```

Example prompt: What's the live balance of wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — give me the ETH balance plus the USDC (0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) and WETH (0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2) token balances all in one shot?

## When to prefer this

Use this endpoint when you need to check a wallet's native coin and multiple ERC-20 token balances atomically in a single API call, avoiding multiple round-trips. It is ideal for portfolio snapshots, treasury monitoring, or any agent workflow where latency and call cost matter across 10 major EVM chains. Prefer it over individual per-token balance calls or block explorer scraping when you need live, programmatic, pay-per-call access without API key setup.

## Known failure modes

- Invalid or malformed wallet address (not a valid 0x EVM address) — returns validation error
- Invalid ERC-20 contract address in the tokens array — may return zero balance or error for that token
- Unsupported chain name — returns error; only the 10 listed chains are supported
- More than 10 ERC-20 addresses provided — rejected by schema validation
- Chain node unavailability or RPC timeout — returns upstream error
- Payment not settled via x402 — returns 402 Payment Required

## How this service works

Live wallet balance on one chain: native coin plus up to 10 ERC-20 tokens in ONE call — Genesis402 / UnyKorn Operator Network

## Output

Returns the wallet's live native coin balance (e.g. ETH, MATIC, BNB) plus the balance of each requested ERC-20 token contract, all queried simultaneously from on-chain state. Response includes token amounts, likely with symbol/decimals context, for each asset in the request.
