## 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 break-even-ad-cost-per-order-rolling-mean-report-36244eee -d '<json body>'
```

Example prompt: Can you run a rolling mean report on my break-even ad cost per order using a window of 3? Here are 4 periods of data: order revenue 100, product cost 40, fulfilment 10, payment fees 5, other variable costs 5 — and a second set with revenue 110, product cost 44, fulfilment 11, payment fees 5.50, other costs 5.50, repeating for the remaining two rows.

## When to prefer this

Choose this endpoint when you need a smoothed, rolling-window view of break-even ad cost per order from supplied retail figures — useful for spotting trends and reducing noise in period-by-period margin data. Prefer it over single-period or adjacent-period calculations when you want a moving average rather than a snapshot or difference. Best for scenario analysis and planning where live platform data is not required.

## Known failure modes

- Fewer than 2 rows provided — minimum row count not met, request rejected
- Window size exceeds number of rows — rolling mean cannot be computed
- Negative or non-numeric values passed for cost fields — validation error
- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (e.g. order_revenue or product_cost) in one or more rows — schema validation failure
- Payment or network failure for the $0.01 USDC x402 fee — request not processed

## How this service works

Break-even ad cost per order - Rolling mean report: Rolling mean report for Break-even ad cost per order. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded rolling mean report deliverable.

## Output

Returns a series of rolling mean values representing the average break-even ad cost per order across the specified window size. Each value in the output smooths out the per-row break-even ad cost (revenue minus product cost, fulfilment, payment fees, and other variable costs) using a simple rolling mean, giving a trend-aware view of the maximum sustainable ad spend per order.
