## 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 verifylite-balance-lookup-42dfd58b -d '<json body>'
```

Example prompt: What's the ETH and USDC balance for 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Base mainnet, and is it a wallet or a contract?

## When to prefer this

Choose this endpoint when you need a quick, single-call summary of an address's financial state on Base mainnet — ETH balance, USDC balance, transaction history depth, and EOA vs. contract classification all in one response. Prefer it over raw RPC calls when you want human-readable formatting alongside raw units without additional conversion logic. Best suited for pre-transaction checks, portfolio snapshots, or identity classification for Base addresses.

## Known failure modes

- Invalid or malformed 0x address returns a 400 error
- Address not found or zero activity returns all-zero balances (not an error, but may appear empty)
- RPC node unavailability causes a 502/503 response
- Payment failure (x402 protocol) blocks the request before execution
- Address with no USDC holdings returns 0 USDC balance without error

## How this service works

Base mainnet balance lookup for one address: ETH and USDC balances (human-readable and raw units), transaction count, and whether the address is a wallet or a contract, at the latest block. Useful for checking that a wallet is funded before a payment, confirming a payout landed, or screening a counterparty. Read-only. Not charged for an invalid address or when Base can't be reached.

## Output

Returns a JSON object containing the ETH balance in ether and wei, USDC balance in human-readable (6 decimal) and raw units, the total transaction count (nonce), a boolean or label indicating whether the address is a contract or an externally owned wallet (EOA), and the block number at which the snapshot was taken.
