## 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

```

Example prompt: Can you calculate my subscription metrics? I have 200 subscribers paying $15 per month and my monthly churn rate is 3%.

## When to prefer this

Choose this endpoint when you need a quick, accurate computation of the three core subscription KPIs (MRR, ARR, monthly churn) from raw inputs without setting up your own formula logic. Ideal for SaaS dashboards, investor reporting, or automated financial pipelines that process subscription data programmatically.

## Known failure modes

- Missing or non-numeric input fields may cause a 400 error or incorrect calculation
- Negative values for subscribers or price may produce nonsensical results
- Very high churn rates (>100%) may not be validated and could produce misleading output
- API unavailability returns a 402 or 5xx error
