## How to call it through Zero

```sh
zero fetch --capability api-deepbluebase-xyz-a0863473
```

Example prompt: Can you scan the wallet portfolio for 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base and show me all the tokens it holds along with the total USD value?

## When to prefer this

Use this endpoint when you need a comprehensive snapshot of all token holdings and total portfolio value for a specific wallet address on the Base chain. Prefer this over individual token price endpoints when you want a full portfolio view in one call. Best for portfolio dashboards, whale watching on Base, or verifying asset composition of a specific address.

## Known failure modes

- Invalid or malformed wallet address returns error or empty result
- Wallet with no Base chain activity returns empty token array with zero values
- Network or RPC issues may return 5xx errors
- Rate limiting or payment failure returns 402 or 429
- Unknown token contracts may be omitted from holdings list
