# 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/nexus/api/v1/standard-error-mean
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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-63f6041d -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 statistical computation of the standard error of the mean without setting up a local statistics library. Suitable for lightweight agent workflows needing on-demand SEM calculations at low cost ($0.002 per call). Not ideal for large-batch or high-frequency statistical pipelines where local computation would be more cost-effective.

## Known failure modes

- Empty array input returns an error or undefined result
- Non-numeric values in the array may cause processing failure
- Array with a single element produces SEM of zero or an undefined result
- Malformed request body causes a 400-level error
- Payment failure via x402 protocol blocks the request

## Output

Returns a JSON object with a 'result' field containing the computed standard error of the mean and a 'status' field confirming success. The result represents how much the sample mean is expected to vary from the true population mean.
