## 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-mean-d82f95e4 -d '<json body>'
```

Example prompt: Can you calculate the arithmetic mean of these numbers for me: 4, 7, 13, 2, 19, 8, 5?

## When to prefer this

Choose this endpoint when you need a quick, low-cost computation of the arithmetic mean for a numeric dataset up to 10,000 values. Ideal for agents performing lightweight statistical summaries without needing a full statistics library or heavy computation environment. Prefer over general-purpose code execution when a fast, dedicated mean calculation with a clean JSON response is required.

## Known failure modes

- Empty array input may return an error or undefined result
- Non-numeric values in the array will cause a validation error
- Array exceeding 10,000 elements will be rejected
- Malformed JSON body returns a 400 Bad Request
- Network or server unavailability returns a 5xx error

## How this service works

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

## Output

Returns a JSON object containing a single 'mean' field with the arithmetic average of the input array as a numeric value (e.g. {"mean": 3}).
