## 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 margin-of-safety-distribution-summary-c323579b -d '<json body>'
```

Example prompt: Can you summarise the distribution of our margin of safety across these 8 quarters? Actual sales were 10000, 11000, 9500, 12000, 10500, 11500, 9000, 13000 and break-even sales were 7000, 7700, 6650, 8400, 7350, 8050, 6300, 9100 — I want the quantiles and standard deviation.

## When to prefer this

Choose this endpoint when you have a batch of pre-computed actual and break-even sales figures (2–200 observations) and need a statistical distribution summary — quantiles and population standard deviation — of the resulting margin of safety values. Prefer it over a single-record calculator when you want to understand variability, spread, or percentile rankings across periods, stores, or business units. Not suitable if you need live financial data, trade execution, or financial advice.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observations required
- More than 200 rows supplied — exceeds maxItems limit
- actual_sales of 0 or negative — excluded by exclusiveMinimum constraint
- Missing required fields actual_sales or break_even_sales in any row
- Non-numeric values passed for sales figures — schema validation failure
- break_even_sales exceeding 1,000,000,000,000 — out of allowed range

## How this service works

Margin of safety - Distribution summary: Summarise up to 200 calculated observations with quantiles and population standard deviation. Metric: Margin of safety. 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 object containing the distribution summary of computed margin-of-safety observations, including quantiles (e.g. min, Q1, median, Q3, max), population standard deviation, the formula used, units, and stated limitations of the analysis.
