## 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 basic-utils-agent-statistics-range-e0fab893 -d '<json body>'
```

Example prompt: Can you calculate the statistical range for this dataset: [3, 7, 1, 5, 9, 4, 2, 8]? I want to know the difference between the highest and lowest values.

## When to prefer this

Use this endpoint when you need a fast, lightweight computation of statistical range (max - min) for a numeric dataset of up to 10,000 values. Prefer it over full statistical suites when only the range is needed and cost efficiency matters at $0.002 per call.

## Known failure modes

- Empty array input returns an error or undefined range
- Non-numeric values in the array cause a validation error
- Array exceeding 10,000 elements may be rejected
- Missing 'data' field in the request body causes a 400 error
- Payment failure (402) if x402 payment header is not included

## How this service works

A versatile utility agent offering calculator, statistics, datetime, and unit conversion services.

## Output

Returns a JSON object with a single 'range' field containing the numeric difference between the maximum and minimum values in the submitted array (e.g. {"range": 4})
