## 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`):

```

Example prompt: Can you compute a rolling mean of net merchandise sales for this series of 4 periods — gross sales were $10,000, $11,000, $10,000, $11,000 with discounts of $500, $550, $500, $550 and returns of $300, $330, $300, $330 — using a window of 2?

## When to prefer this

Choose this endpoint when you need a quick, local rolling mean computation on retail net merchandise sales data you already have. It is ideal for smoothing time-series sales figures across multiple periods, performing offline scenario analysis, or preparing trend summaries without requiring live inventory, platform account, or order execution access. It is not suitable for fetching live sales data, querying platform fees, or executing transactions.

## Known failure modes

- Fewer than 2 rows supplied — minimum row count not met
- Window size exceeds number of rows — rolling window cannot be applied
- Negative values for discounts or returns — violates minimum=0 constraint
- Any of gross_merchandise_sales, discounts, or returns missing from a row — required fields not satisfied
- Values exceed maximum threshold of 1,000,000,000,000 — out of bounds error
- Non-numeric values in numeric fields — schema validation failure
