## 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-profit-adjacent-period-changes-calculator-7b964dac -d '<json body>'
```

Example prompt: I have four quarters of financial data — Q1 through Q4 — with revenues of 10000, 11000, 10000, 11000 and corresponding cost of sales of 6000, 6600, 6000, 6600 and operating expenses of 2000, 2200, 2000, 2200. Can you calculate the adjacent period changes in operating profit for each consecutive quarter pair, including the percent changes?

## When to prefer this

Choose this endpoint when you have a series of 2–200 consecutive financial periods and need a structured, formula-documented report of operating profit changes between adjacent periods without any interpolation or forecasting. It is ideal when you want a bounded, auditable snapshot of period-over-period operating profit shifts delivered as JSON with explicit limitations noted.

## Known failure modes

- Fewer than 2 rows supplied — minimum requirement not met
- Revenue or cost values exceed the ±1,000,000,000,000 boundary
- Non-numeric values passed for revenue, cost_of_sales, or operating_expenses
- Percent change not calculable when base period operating profit is zero (division by zero)
- Too many rows — maximum of 200 items exceeded

## How this service works

Operating profit - Adjacent period changes: Report adjacent-observation differences and eligible percent changes; no interpolation. Metric: Operating profit. 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 adjacent period changes report.

## Output

A JSON response containing the formula used to derive operating profit, the adjacent period absolute differences and eligible percent changes between consecutive data rows, the units of measurement, and limitations of the analysis (e.g. no interpolation, supplied figures only).
