## 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-sales-units-distribution-summary-b9376132 -d '<json body>'
```

Example prompt: I have 5 pricing scenarios for my product — unit prices of 20, 22, 25, 18, and 30 with corresponding fixed costs of 5000, 5500, 6000, 4500, and 7000 and variable costs per unit of 12, 13.20, 15, 11, and 18 — can you run a break-even units distribution summary across all of them and tell me the quantiles and standard deviation?

## When to prefer this

Choose this endpoint when you need a statistical distribution summary (quantiles + standard deviation) across multiple break-even scenarios rather than a single break-even calculation. It is specifically designed for batch analysis of 2–200 observations and returns structured JSON with formula and limitation metadata, making it ideal for sensitivity analysis, Monte Carlo summaries, or comparing cost structures across many configurations.

## Known failure modes

- Fewer than 2 rows submitted — minimum 2 observations required
- More than 200 rows submitted — exceeds maxItems limit
- Unit price of zero or negative — exclusiveMinimum constraint violated
- Fixed costs or variable costs exceed 1,000,000,000,000 — maximum constraint violated
- Variable cost per unit equals or exceeds unit price — results in undefined or infinite break-even units
- Malformed row objects or missing required fields (fixed_costs, unit_price, variable_cost_per_unit)
- Payment failure — 0.01 USDC not supplied or x402 payment rejected

## How this service works

Break-even sales units - Distribution summary: Summarise up to 200 calculated observations with quantiles and population standard deviation. Metric: Break-even sales units. 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

Returns a JSON object containing a distribution summary of break-even unit calculations across all submitted rows, including quantiles (e.g. min, Q1, median, Q3, max) and population standard deviation, along with the formula used, units, and applicable limitations.
