## 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-churn-rate-calculator-f971cb6c -d '<json body>'
```

Example prompt: We started the quarter with 2000 customers and lost 100 — can you calculate our churn rate for me?

## When to prefer this

Use this endpoint when you need a quick, accurate churn rate KPI calculation without building your own formula. It is ideal for business analytics agents that process customer retention data, generate investor reports, or monitor subscription health. Prefer this over manual computation when churn rate needs to be derived programmatically from raw customer counts.

## Known failure modes

- Missing required fields (customers_lost or total_customers_start) results in a validation error
- Division by zero if total_customers_start is 0
- Negative or non-integer values may cause unexpected results
- customers_lost greater than total_customers_start may return a churn rate above 1.0 (>100%)
