## How to call it through Zero

```sh
zero fetch --capability control-operativo-margin-calculator-f8387305
```

Example prompt: My asadero brought in $5,000 in revenue this month, with $1,800 in variable costs and $1,200 in fixed costs across 200 units sold — can you calculate my gross margin, net margin, and break-even point?

## When to prefer this

Choose this endpoint when you need a fast, structured profitability computation for a food-service or small-business context — especially when you want gross margin, net margin, and break-even metrics in a single call without setting up a spreadsheet or accounting system. It is particularly suited to restaurant and asadero operators wanting per-period margin snapshots programmatically.

## Known failure modes

- Missing required query parameters (revenue, variable_costs, fixed_costs, units) returns an error
- Non-numeric or zero-value units causes validation failure due to regex pattern requiring positive integers
- Revenue or cost values in wrong format (e.g. negative numbers or non-numeric strings) fail schema validation
- Network or payment processing failure may result in no response or unpaid transaction
- Edge case: variable_costs + fixed_costs exceeding revenue returns valid result with negative net profit
