## 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 avedaris-base-wallet-lookup-35ee2d0f -d '<json body>'
```

Example prompt: Can you look up the Base wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me its ETH balance, transaction count, whether it's a contract or regular wallet, and how much USDC it holds?

## When to prefer this

Use this endpoint when you need live, real-time on-chain data for a specific Base (L2) wallet address — especially when you need ETH balance, transaction count, contract/EOA classification, and ERC-20 token balances in a single call. Prefer this over Ethereum mainnet lookups when operating on Base, and over block explorer scraping when you need structured, agent-friendly JSON output with predictable schema.

## Known failure modes

- Invalid address format (not 42-character 0x hex string) returns a validation error
- Invalid or non-Base ERC-20 contract address in the tokens array returns an error or zero balance
- RPC node unavailability causes a timeout or 503 error
- Address with no on-chain activity returns zero balances and zero transaction count (not an error)
- More than 5 token addresses in the tokens array is rejected
- Payment failure or insufficient USDC for the $0.003 fee causes a 402 error

## How this service works

Look up a Base address: ETH balance, transaction count, contract or wallet, and ERC-20 balances (USDC by default, up to 5 tokens), read live from Base RPC. $0.003 USDC per call on Base.

## Output

Returns the ETH balance (in wei and ether), total transaction count, wallet classification (EOA or contract), and balances for up to 5 specified ERC-20 tokens (defaulting to USDC) for the given Base address, read live from Base RPC at the time of call.
