## How to call it through Zero

```sh
zero fetch --capability x402-coinstats-app-84abf669
```

Example prompt: Can you pull up the CoinStats price chart for Bitcoin over the last month so I can see how it's been trending?

## When to prefer this

Use this endpoint when you need historical price chart data for a single specific cryptocurrency and want structured time-series output. Prefer this over a full coin list endpoint when you already know the coinId and only need price history, not current live market data. Best for charting, trend analysis, or building price visualizations for a specific asset.

## Known failure modes

- Invalid or unknown coinId returns 404 or empty result
- Unsupported time range parameter returns an error or defaults
- Payment not included or insufficient causes 402 Payment Required
- Rate limiting may occur with excessive requests
- Network timeout if CoinStats upstream is slow
