## 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 losbeto-chain-balance-wallet-intelligence-63294ef3
```

Example prompt: What's the ETH balance, USDC and WETH holdings, and wallet class for 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD on Base — is it a whale, degen, or newcomer?

## When to prefer this

Choose this endpoint when you need a single enriched snapshot of a Base wallet — combining raw balances, activity level, and a pre-computed wallet classification — rather than making separate RPC calls for each data type. Ideal for DeFi agents doing credit profiling, airdrop eligibility checks, whale detection, or onboarding KYC-lite flows where wallet behavior matters as much as raw balance.

## Known failure modes

- Invalid or malformed address returns an error — must be a valid EVM 0x address
- Unsupported network (non-Base chain) may return empty or incorrect results
- More than 20 tokens requested exceeds the batch limit
- Unregistered ENS returns null for reverse ENS field
- RPC timeout on Base may cause delayed or failed response
- Invalid token contract addresses in the tokens parameter return zero balances

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.

## Output

A JSON object containing: native ETH balance, balances for up to 20 ERC-20 tokens (defaulting to USDC, WETH, cbBTC), transaction count (nonce), a heuristic wallet_class label (one of: ghost, newcomer, steady, degen, whale), and reverse ENS name if set for the address on Base.
