Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-mode-75155303 -d '<json body>'
```

Example prompt: What is the mode of this dataset: [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5]? I need to find which number appears most frequently.

## When to prefer this

Use this endpoint when you need a dedicated, fast, pay-per-call statistical mode computation without setting up your own math library. Ideal for AI agents that need on-demand descriptive statistics as part of a larger data analysis workflow, particularly when the agent does not have native math capabilities. Supports up to 10,000 data points per call, making it suitable for moderate-sized datasets.

## Known failure modes

- Empty array input may return an error or empty mode result
- Extremely large arrays (over 10,000 elements) will be rejected
- Non-numeric values in the array will cause a validation error
- Malformed request body will return a 400-level error
- All values equally frequent may return all values as mode or an empty result

## How this service works

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

## Output

Returns a JSON object with a 'mode' field containing an array of the most frequently occurring value(s) in the input dataset. If multiple values tie for most frequent, all are returned in the array.
