## 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-benchmark-correlation-calculator-6ad8513a -d '<json body>'
```

Example prompt: Can you calculate the Pearson correlation between my company's operating margin and these industry benchmarks — my revenue and operating profit pairs are [10000/2000, 11000/2500, 12000/2800, 13000/3100] and the benchmarks are [18, 20, 22, 24]? I want the formula, units, and any limitations in the output.

## When to prefer this

Choose this endpoint when you need a rigorous, formula-documented Pearson correlation between a computed operating margin series and externally supplied benchmark values, and you want a bounded report with explicit limitations rather than a predictive or advisory output. It is ideal for compliance-conscious financial reporting, investor documentation, or audit trails where the method must be transparent and no causal inference is claimed.

## Known failure modes

- Fewer than 2 rows or benchmarks supplied — minimum items validation error
- Mismatched array lengths between rows and benchmarks causing correlation failure
- Revenue value of zero or below excluded by exclusiveMinimum constraint
- Operating profit or revenue values exceeding maximum bounds rejected
- Malformed input JSON returns validation error
- Benchmarks array length does not align with rows array length

## How this service works

Operating margin - Benchmark correlation: Calculate Pearson correlation against aligned supplied benchmarks; no causal or predictive claim. 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 benchmark correlation report.

## Output

Returns a JSON object containing the Pearson correlation coefficient between the calculated operating margin series and the supplied benchmark values, along with the formula used, measurement units, and explicit limitations (e.g., no causal or predictive claim is made).
