## 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 operating-margin-before-and-after-comparison-calculator-0dd68c09 -d '<json body>'
```

Example prompt: Can you compare our operating margin before and after our cost restructuring? Before, we had revenue of $10 million and operating profit of $1.5 million; after, revenue was $11 million and operating profit was $2.4 million.

## When to prefer this

Choose this endpoint when you need a structured, formula-documented comparison of operating margin between exactly two discrete time periods or scenarios. It is ideal for before-and-after analysis (e.g., pre/post restructuring, year-over-year, quarter-over-quarter) where you have both revenue and operating profit figures for each period and need absolute and relative change metrics with transparent methodology. Prefer it over generic calculators when audit-trail documentation (formula, units, limitations) matters for reporting.

## Known failure modes

- Revenue value of zero or missing causes division error
- Negative revenue not accepted (exclusiveMinimum: 0)
- Operating profit exceeds maximum bounds (±1 trillion)
- Missing required fields (operating_profit or revenue in either record) returns validation error
- Supplying non-numeric values for financial figures causes schema rejection

## How this service works

Operating margin - Before and after comparison: Compare two supplied records, reporting absolute and eligible relative changes. Metric: Operating margin. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded before and after comparison report.

## Output

A JSON report containing the calculated operating margin for both the before and after periods, the absolute percentage-point change, the eligible relative change, the formula used, units, and any applicable limitations of the comparison.
