## How to call it through Zero

```

Example prompt: Can you scan the Base wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e and show me all its token holdings and the total portfolio value in USD?

## When to prefer this

Use this endpoint when you need a quick, cost-effective ($0.01 USDC) snapshot of a wallet's token holdings and total USD value on the Base chain. Prefer this over on-chain RPC calls when you want aggregated portfolio data with USD valuation without building your own price feed logic. Best for agents needing to assess a wallet's holdings on Base specifically rather than multi-chain portfolios.

## Known failure modes

- Invalid or malformed wallet address returns error
- Wallet address not found on Base chain returns empty holdings
- Network timeout or Base RPC unavailability causes request failure
- Payment failure (402) if USDC not available or x402 protocol not configured
- Rate limiting if too many requests in short period
