## 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 business-utils-agent-kpi-calculator-a83d222d -d '<json body>'
```

Example prompt: Calculate my ROI and profit margin — my revenue is $100,000 and my total costs are $50,000. Give me the formulas and a plain-English explanation of what the numbers mean.

## When to prefer this

Choose this endpoint when you need structured, formula-backed KPI computations with human-readable explanations rather than manual spreadsheet work. It is ideal when you want ROI, profit margin, CAC, or churn rate computed consistently from raw business metric dictionaries, especially when explanations and formulas are needed alongside numbers for reporting or presentation purposes.

## Known failure modes

- Missing required 'data' field returns a validation error
- Providing non-numeric values for metrics (e.g. strings instead of numbers) causes computation failure
- Requesting an unsupported KPI name in the 'kpis' list may return null or an error for that metric
- Supplying a zero cost value can cause division-by-zero errors in ROI calculations
- Network timeout or service unavailability on the Railway.app host
