Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 inventory-turnover-weighted-result-mean-calculator-2d28d8df -d '<json body>'
```

Example prompt: Calculate the weighted mean inventory turnover for these four periods: cost_of_sales 30000 with avg_inventory 5000, cost_of_sales 33000 with avg_inventory 5500, repeated twice — weight the first and third periods at 1 and the second and fourth at 2.

## When to prefer this

Choose this endpoint when you need a statistically weighted aggregation of multiple inventory turnover observations — for example, combining results across divisions, time periods, or product lines where each observation should carry a different importance. It is not for pooled accounting ratios or live financial data; prefer it when you have pre-computed or directly supplied cost_of_sales and average_inventory pairs that need to be blended with custom weights.

## Known failure modes

- Mismatched array lengths between rows and weights arrays
- Average inventory value of zero triggers exclusiveMinimum validation error
- Fewer than 2 rows or weights submitted
- Values exceeding the maximum of 1,000,000,000,000
- Negative weights or inventory values rejected by schema
- Payment failure or insufficient USDC balance

## How this service works

Inventory turnover - Weighted result mean: Calculate a mean of up to 200 results using supplied nonnegative weights; not a pooled accounting ratio. Metric: Inventory turnover. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded weighted result mean report.

## Output

Returns a JSON object containing the weighted mean inventory turnover value, the formula applied, units used, and a limitations note clarifying that this is not a pooled accounting ratio but a weighted arithmetic mean of the supplied figures only.
