## 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 cryptointel-portfolio-base-wallet-holdings-breakdown-7490717c
```

Example prompt: Can you pull up the full portfolio breakdown for Base wallet 0x4e5F3b6c2A9d1F8e7C0bA3D2E5F6G7H8I9J0K1L2 — I want to see the ETH balance and what tokens it's holding?

## When to prefer this

Use this endpoint when you need a quick, structured snapshot of what tokens and ETH a specific Base wallet holds, especially for portfolio analysis, due diligence on a wallet, or building exposure summaries. Prefer this over the premium bundle when you only need holdings data and want to minimize cost.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Wallet address not on Base network may return empty or zero balances
- Rate limiting or payment failure (x402) if USDC payment is not processed
- Newly created wallet with no activity may return minimal data
- Network or upstream RPC timeout resulting in a 5xx error

## How this service works

Wallet holdings breakdown on Base: ETH balance, tx count

## Output

Returns a JSON object with the wallet's ETH balance on Base, a list of top token holdings with quantities/values, and a basic exposure summary indicating the wallet's crypto asset distribution.
