## 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 saylor-innovations-break-even-calculator-d1bd88e1
```

Example prompt: Can you run a break-even analysis for my product? The selling price is $45 per unit, variable cost is $18 per unit, and fixed costs are $27,000 per month. I'd also like to know how many units I need to sell to hit a $10,000 profit target.

## When to prefer this

Choose this endpoint when you need a fast, straightforward break-even analysis with contribution margin and optional target-profit output. It is ideal for small business planning, product pricing decisions, and financial feasibility checks where the user has a clear selling price, variable cost, and fixed cost. It is a simple formula-based computation, not a full financial model, so prefer it over spreadsheet tools or full accounting APIs when speed and simplicity matter.

## Known failure modes

- Missing required parameters (price, variable_cost, fixed_cost) returns a validation error
- Price less than or equal to variable cost results in zero or negative contribution margin, making break-even undefined or infinite
- Negative values for price or costs may return an error or undefined result
- Non-numeric string values for numeric parameters will cause a parse or validation error

## How this service works

Break-even calculator - contribution margin, break-even units and revenue, and target-profit units

## Output

Returns a JSON object with the unit price, variable cost per unit, fixed cost, target profit, contribution margin per unit, contribution margin as a percentage, break-even units, break-even revenue, target-profit units, target-profit revenue, the formula used, and a scope note clarifying what the calculation covers and excludes.
