## 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 x402-coinstats-app-1af54dea
```

Example prompt: Can you pull up the historical USD value chart and PnL for my Ethereum wallet 0xAbc123...def456 over the past month using CoinStats?

## When to prefer this

Use this endpoint when you need historical portfolio value and PnL specifically for a single wallet address. Prefer this over the multi-wallet chart endpoint when analyzing one wallet in isolation. Ideal for tracking performance of a specific address without needing a CoinStats shared portfolio token.

## Known failure modes

- Invalid or unrecognized wallet address returns empty or error response
- Unsupported blockchain for wallet lookup
- Payment of 0.004 USDC via x402 not completed results in 402 Payment Required
- Rate limiting or quota exceeded
- Wallet has no transaction history or balance returns empty chart
- Invalid time period parameter
