## 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 x402toll-break-even-analysis-cvp-438383ec -d '<json body>'
```

Example prompt: My business has $12,000 in fixed costs per month, I sell each product for $45, and my variable cost per unit is $18 — can you calculate my break-even point in units and revenue?

## When to prefer this

Use this endpoint when you need a quick, accurate CVP break-even computation given fixed costs, selling price, and variable cost per unit. Ideal for entrepreneurs, product managers, or financial analysts who want to know the minimum sales volume required for profitability without building a full financial model.

## Known failure modes

- Price per unit equals variable cost per unit (zero contribution margin, division by zero — no break-even exists)
- Variable cost per unit exceeds price per unit (negative contribution margin — break-even is not achievable)
- Missing required fields (fixedCosts, pricePerUnit, or variableCostPerUnit not provided)
- Negative input values causing nonsensical results
- Non-numeric inputs causing schema validation failure

## How this service works

Break-even units and revenue (CVP): where contribution margin covers fixed costs.

## Output

Returns the break-even number of units that must be sold and the corresponding break-even revenue, computed from the contribution margin (price per unit minus variable cost per unit) relative to fixed costs.
