## 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 portfolio-24h-pnl-unrealized-p-l-on-base-wallet-311bda3e -d '<json body>'
```

Example prompt: How is my portfolio doing today? Check the 24h unrealized PnL for my Base wallet 0x1234...abcd and tell me which holdings are the biggest movers.

## When to prefer this

Use this endpoint when you need a quick snapshot of how a specific Base wallet's holdings have performed over the past 24 hours, including unrealized PnL in USD and percentage terms and which positions moved the most. Prefer this over raw transaction history endpoints when the goal is performance analytics rather than activity logging.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Wallet with no tracked holdings returns zero or empty results
- Pricing data unavailable for an exotic token causes partial results
- Payment not included or insufficient USDC triggers a 402 payment required response
- Network timeout if Base RPC or price feeds are slow
