## 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 freelancer-break-even-units-calculator-ca9e4f52 -d '<json body>'
```

Example prompt: I have $500 in fixed monthly costs, I charge $25 per unit, and my variable cost per unit is $10 — how many units do I need to sell to break even?

## When to prefer this

Choose this endpoint when you need a fast, single-call break-even computation specifically framed for freelance or per-unit service workflows. It is ideal when you already know your fixed costs, selling price, and variable cost per unit and simply need the break-even quantity. Prefer alternatives if you need multi-scenario sensitivity analysis, revenue projections, or profit forecasts beyond the break-even point.

## Known failure modes

- Contribution margin of zero (price equals variable cost) causes division by zero — endpoint likely returns an error or undefined result
- Negative contribution margin (variable cost exceeds price) produces a nonsensical negative break-even count — caller should validate inputs
- Missing required fields default to preset values (fixed_cost=500, price_per_unit=25, variable_cost_per_unit=10) which may silently produce irrelevant results
- Non-numeric inputs will likely cause a validation or parsing error

## How this service works

Freelancer Break-even units calculator: Calculate units needed to cover fixed costs from contribution per unit. Tailored for freelancer workflows.

## Output

Returns the number of units required to cover all fixed costs, derived from dividing fixed costs by the contribution margin (price per unit minus variable cost per unit). Typically includes the break-even unit count and the underlying contribution per unit used in the calculation.
