## 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-b3b2de0a -d '<json body>'
```

Example prompt: Show me a balance chart for my CoinStats-connected exchange account over the past month — I want to see how my total holdings have changed over time.

## When to prefer this

Use this endpoint when you need historical balance chart data specifically for a cryptocurrency exchange account (e.g. Binance, Coinbase, Kraken) connected via CoinStats, as opposed to a wallet address or shared portfolio. Best when the user wants to visualize how their exchange holdings have changed over a defined time period.

## Known failure modes

- Missing or invalid sharetoken header returns authentication error
- Exchange account not connected or synced returns empty or error response
- Invalid time range parameter causes malformed request error
- Exchange sync not completed may return stale or incomplete data
- Rate limiting or payment failure returns 402 or 429 error
