# KiHustle Standard Error of the Mean Calculator

> KiHustle Standard Error of the Mean Calculator is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Computes the standard error of the mean (SEM) for a given array of numeric values

## Facts

- Endpoint: POST https://kihustle.tech/agents/api/v1/standard-error-mean
- Price: $0.002/call
- Payment: x402

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 kihustle-standard-error-of-the-mean-calculator-4bef0b7e -d '<json body>'
```

Example prompt: Can you calculate the standard error of the mean for these values: 12.4, 15.1, 13.8, 14.2, 11.9, 16.0, 13.5?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call computation of the standard error of the mean without setting up your own statistics library or environment. Useful in lightweight agent pipelines that need on-demand statistical calculations for small to medium datasets.

## Known failure modes

- Empty array input — cannot compute SEM with no values
- Single-value array — standard deviation is undefined for n=1, may return error or zero
- Non-numeric values in array — input validation failure
- Missing 'values' field in request body — returns error
- Very large arrays may cause timeout or processing delay

## Output

Returns a JSON object with a 'result' field containing the computed standard error of the mean and a 'status' field indicating success. The SEM is derived from the provided array of numeric values.
