## 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-single-calculation-8ce98df8 -d '<json body>'
```

Example prompt: Can you calculate the degree of operating leverage for me? My contribution margin is $5,000 and operating profit is $2,000.

## When to prefer this

Choose this endpoint when you need a fast, single-record DOL computation with a clear formula and units breakdown returned as structured JSON. It is ideal for one-off checks, embedded calculations in financial reports, or agent workflows that need a precise leverage ratio without the overhead of batch processing, sensitivity tables, or histogram analysis.

## Known failure modes

- Operating profit of zero or negative will be rejected (exclusiveMinimum: 0 enforced)
- Values exceeding ±1 trillion will be rejected by schema validation
- Missing required fields (contribution or operating_profit) will result in a 400-level error
- Inconsistent currency or reporting period between the two inputs may produce a mathematically valid but economically meaningless result
