## 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 pricing-math-break-even-analysis-cb2f2b4c
```

Example prompt: I have $12,000 in fixed costs this month, I'm selling each unit for $45, and my variable cost per unit is $18. How many units do I need to sell to break even, and what if I want to hit a $3,000 profit target on top of that?

## When to prefer this

Use this endpoint when you need a quick, reliable break-even computation given known fixed costs, a unit selling price, and a variable cost — especially when you also want to model a specific profit target. Prefer this over manual spreadsheet calculations or general-purpose LLM math when you need structured, field-level output (contribution margin %, whole-unit rounding, revenue figures) that can be passed downstream to other agents or displayed in a dashboard.

## Known failure modes

- Missing required query params (fixedCosts, price, variableCost) returns a validation error
- Price equal to or less than variable cost results in undefined or infinite break-even (zero or negative contribution margin)
- Non-numeric parameter values cause a bad request error
- Very large or very small numbers may return degraded accuracy indicated by the degraded flag

## How this service works

Break-even units and revenue from fixed costs, price and variable cost per unit, with an optional profit target.

## Output

Returns the number of units needed to break even (exact and rounded up to whole units), break-even revenue, contribution per unit, contribution margin percentage, revenue at whole units, and optionally the units/revenue needed to hit a target profit. Also includes summary and verdict fields describing the result.
