# Customer Churn Rate Benchmark Correlation Calculator

> Customer Churn Rate Benchmark Correlation Calculator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Calculates Pearson correlation between customer churn rate data and user-supplied benchmark values, returning the formula, units, and statistical limitations.

## 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-benchmark-correlation-calculator-8f3e959a -d '<json body>'
```

Example prompt: Calculate the Pearson correlation between my customer churn rates and these industry benchmarks — for the last 4 quarters my lost customers were 5, 6, 4, 7 out of opening customers of 100, 110, 95, 120, and the benchmarks are 10, 12, 9, 14.

## When to prefer this

Choose this endpoint when you need a bounded statistical correlation (Pearson) between your own customer churn rate time-series and a set of external or industry benchmark values — especially when you only need the correlation coefficient with formula and limitations, not predictive modeling or live data. Prefer this over general-purpose stats tools when you want a single-call, low-cost ($0.01 USDC) churn-specific correlation report with explicit disclaimers baked in.

## Known failure modes

- Fewer than 2 rows or benchmark values provided — minimum 2 data points required
- Mismatched array lengths between rows and benchmarks — lengths must align
- opening_customers value of zero — field requires exclusiveMinimum of 0
- Values exceeding maximum bounds (1e12 for customers) return validation error
- Non-numeric values in rows or benchmarks cause schema rejection

## How this service works

Customer churn rate - Benchmark correlation: Calculate Pearson correlation against aligned supplied benchmarks; no causal or predictive claim. 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 benchmark correlation report.

## Output

A JSON object containing the Pearson correlation coefficient between the computed churn rates and the supplied benchmark values, along with the formula used, units, and explicit statistical limitations (no causal or predictive claims).
