## How to call it through Zero

```sh
zero fetch --capability x402-coinstats-app-9a41705c
```

Example prompt: Pull the historical coin balance snapshot for my shared CoinStats portfolio — I'm on the Degen plan and want to see how my holdings in each coin have changed over time.

## When to prefer this

Use this endpoint when you need to see how coin holdings in a specific shared CoinStats portfolio have evolved over time — particularly useful for auditing, tax reporting, performance tracking, or visualizing balance changes. Prefer this over the portfolio value chart endpoint when you need per-coin balance data rather than aggregate USD value.

## Known failure modes

- Missing or invalid sharetoken header returns authentication error
- Non-Degen-plan sharetoken returns authorization/plan error
- Expired or revoked sharetoken returns 401 or 403
- No historical snapshot data available for the portfolio returns empty list
- Payment not processed (x402 payment required) returns 402
