## 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 degree-of-operating-leverage-before-after-comparison-d119e4f0 -d '<json body>'
```

Example prompt: Can you compare my degree of operating leverage before and after a change? Before: contribution was 5000 and operating profit was 2000. After: contribution is 5500 and operating profit is 2200. Give me the absolute and relative change with the formula and any limitations.

## When to prefer this

Choose this endpoint when you need a structured, formula-accompanied comparison of degree of operating leverage across exactly two time periods or scenarios using user-supplied figures. It is ideal for one-off analytical queries where no live financial data feed is needed and you want an auditable JSON result with limitations disclosed. Prefer alternatives if you need real-time data ingestion, multi-period trend analysis, or financial advice.

## Known failure modes

- Operating profit of zero or below will be rejected (minimum is exclusive of 0)
- Contribution or operating profit values outside ±1 trillion will be rejected
- Missing required fields (contribution or operating_profit in either before or after object) returns a validation error
- Supplying mismatched currencies or reporting periods produces mathematically valid but economically meaningless output — no warning is given

## How this service works

Degree of operating leverage - Before and after comparison: Compare two supplied records, reporting absolute and eligible relative changes. Metric: Degree of operating leverage. 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 object containing the computed degree of operating leverage for both the before and after periods, the absolute change, the eligible relative change, the formula used, units, and any applicable limitations of the metric.
