Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-1e936152 -d '<json body>'
```

Example prompt: What's the current position for wallet 0xAbC...123 on the WETH token — give me the balance, estimated PnL, and approximate entry price.

## When to prefer this

Choose this endpoint when you need a quick, combined view of a wallet's token position including balance, estimated PnL, and entry price — especially in DeFi monitoring workflows where you need all three metrics in a single call rather than stitching together separate balance and transaction history queries.

## Known failure modes

- Invalid or unrecognized wallet address returns an error
- Token address not found on the specified chain
- Insufficient on-chain transaction history to compute entry price approximation
- Chain not supported returns 400 or unsupported chain error
- Payment of 0.25 USDC not completed returns 402 Payment Required
- Rate limiting or service unavailability returns 503

## Output

Returns the wallet's current token balance, an estimated profit-and-loss figure, and an approximated entry price for the specified token position, enabling assessment of unrealized gains or losses.
