## 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-iqr-outlier-flags-calculator-bd015c19 -d '<json body>'
```

Example prompt: Can you flag any statistical outlier periods in our churn data using the IQR method? I have 6 months of figures: lost_customers were 5, 6, 50, 5, 6, 5 and opening_customers were 100, 110, 105, 100, 108, 102.

## When to prefer this

Choose this endpoint when you need a fast, low-cost statistical outlier screen on customer churn rate time-series or cohort data using the standard IQR method. It is ideal for pre-analysis data quality checks, anomaly triage in churn dashboards, or preparing clean datasets before deeper modeling. It does not provide fraud detection, financial advice, or real-time data — use it purely for bounded statistical flagging of supplied figures.

## Known failure modes

- Fewer than 2 rows submitted (minItems violation)
- More than 200 rows submitted (maxItems violation)
- opening_customers value of 0 (exclusiveMinimum violation causing division-by-zero)
- Negative values for lost_customers or opening_customers
- Non-numeric values in required fields
- Payment not included or insufficient USDC balance

## How this service works

Customer churn rate - IQR outlier flags: Flag observations beyond 1.5 times the interquartile range; statistical flags are not errors or fraud findings. 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 iqr outlier flags report.

## Output

Returns a JSON object containing IQR outlier flags for each submitted churn rate observation, along with the formula used, units, and stated limitations of the statistical method. Flags indicate which rows fall beyond 1.5× the interquartile range of the computed churn rates.
