## 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 operating-margin-distribution-summary-calculator-0a7f5df2 -d '<json body>'
```

Example prompt: Can you give me a distribution summary of operating margins for these 5 observations — operating profits of 2000, 2200, 1800, 2500, 1900 against revenues of 10000, 11000, 9000, 12000, 9500? I want the quantiles and standard deviation.

## When to prefer this

Choose this endpoint when you have a batch of operating profit and revenue pairs and need a statistical distribution summary (quantiles, standard deviation) rather than a single point calculation. It is ideal for cross-sectional peer analysis, time-series volatility assessment, or portfolio screening where understanding the spread and shape of operating margins matters. Prefer this over a single-observation calculator when you have 2–200 data points and want aggregate statistics in one call.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 observations required
- Revenue value is zero or negative — revenue must be strictly greater than 0
- More than 200 rows submitted — exceeds maximum item limit
- Values outside allowed range — operating profit or revenue exceeds magnitude bounds
- Malformed input — missing required fields operating_profit or revenue in one or more rows

## How this service works

Operating margin - Distribution summary: Summarise up to 200 calculated observations with quantiles and population standard deviation. Metric: Operating margin. 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 distribution summary report.

## Output

A JSON response containing a distribution summary of up to 200 calculated operating margin observations, including quantiles (e.g. min, Q1, median, Q3, max), population standard deviation, the formula used to compute operating margin, units, and any limitations on the calculation.
