## 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 defi-shield-hazel-vercel-app-97a63aa5 -d '<json body>'
```

Example prompt: What's the profit and loss breakdown per token for wallet 0xAbc123...? I want to see exactly which tokens I've made money on and which I've lost money on.

## When to prefer this

Use this endpoint when you need a detailed, per-token profit and loss breakdown for a specific wallet address — particularly useful for DeFi portfolio auditing, tax reporting prep, or performance analysis. Prefer this over generic portfolio trackers when you need structured PnL data programmatically per token.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet with no transaction history may return empty or zero PnL
- Network errors or blockchain RPC timeouts may cause failures
- Payment of $1 USDC required per call — failure to pay returns 402
- Unsupported chain or token may result in incomplete data

## Output

Returns a per-token breakdown of profit and loss for the specified wallet, including realized and unrealized gains/losses for each token held or traded.
