## 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 net-margin-before-and-after-comparison-calculator-4f007758 -d '<json body>'
```

Example prompt: Compare our net margin before and after a recent change: before we had revenue of $10,000 and net profit of $1,500, and after we had revenue of $12,000 and net profit of $2,400 — show me the absolute and relative change.

## When to prefer this

Choose this endpoint when you need a fast, structured before-and-after net margin comparison from two sets of supplied figures, with formula transparency and stated limitations included in the response. It is ideal when you already have both periods' revenue and net profit on hand and want a single bounded report rather than a full historical data pull or live financial feed. Prefer alternatives if you need live data ingestion, multi-period trend analysis, or financial advice.

## Known failure modes

- Revenue value of zero or missing will cause validation failure since revenue must be strictly greater than zero
- Net profit or revenue values exceeding 1,000,000,000,000 will be rejected by schema bounds
- Missing required fields (net_profit or revenue) in either before or after object will return an error
- Non-numeric values for revenue or net profit will fail schema validation
- Payment failure or insufficient USDC balance may prevent the call from completing

## How this service works

Net margin - Before and after comparison: Compare two supplied records, reporting absolute and eligible relative changes. Metric: Net 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 object containing the net margin for both the before and after periods (calculated as net profit divided by revenue), the absolute change in net margin (percentage points), the eligible relative change, along with the formula used, units, and any stated limitations of the calculation.
