## 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 customer-churn-rate-before-and-after-comparison-calculator-47082a88 -d '<json body>'
```

Example prompt: We had 100 customers at the start of last quarter and lost 10; this quarter we started with 120 and lost 8 — can you compare our customer churn rate before and after and show me the absolute and relative change?

## When to prefer this

Choose this endpoint when you need a structured, formula-accompanied before-and-after comparison of customer churn rate using two supplied data snapshots. It is ideal for agents that need a reliable, audit-friendly JSON response with explicit formula and limitation disclosures rather than a raw calculation. It does not require live data feeds and works purely from user-supplied figures.

## Known failure modes

- opening_customers must be greater than 0 (exclusive minimum); passing 0 causes a validation error
- lost_customers exceeding opening_customers may produce churn rates over 100%, which the API may flag as a limitation
- missing required fields (lost_customers or opening_customers in either before or after object) will cause a schema validation error
- values exceeding 1,000,000,000,000 are out of range and will be rejected

## How this service works

Customer churn rate - Before and after comparison: Compare two supplied records, reporting absolute and eligible relative changes. Metric: Customer churn rate. 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 churn rate for the 'before' and 'after' periods, the absolute change (percentage point difference), the relative change (where mathematically eligible), the formula used, units, and stated limitations of the calculation.
