## 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-lookup-cac59946
```

Example prompt: What's the ETH balance of wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — and can you show me the USD value too?

## When to prefer this

Use this endpoint when you need a quick, no-account, pay-per-call native token balance check for any EVM-compatible wallet across Ethereum, Base, Polygon, Arbitrum, Optimism, or BSC. Prefer it over block explorer APIs when you want micropayment-gated access without API key management, or when building autonomous agents that need on-chain balance data on-demand.

## Known failure modes

- Invalid or malformed wallet address (not 0x-prefixed or not 42 characters) returns an error
- Unsupported network value returns a validation error
- Address with no on-chain history may return a zero balance
- Live USD price fetch failure may cause with_usd=true requests to fail or return null for USD value
- Rate limiting or upstream RPC node unavailability may cause transient errors
- Payment failure (insufficient USDC or bad x402 header) results in 402 response

## How this service works

Returns the native token balance (ETH, POL, BNB) for any EVM wallet address. Supports Ethereum, Base, Polygon, Arbitrum, Optimism, and BSC. Includes optional USD value. $0.002/call — 60% below comparable market rate. Free upstreams: DRPC + CoinGecko, no API key required.

## Output

Returns the native token balance of the queried wallet address on the specified EVM-compatible network. If with_usd is true, also returns the live USD equivalent of the balance, fetched at query time.
