# Z-Score Calculator

> Z-Score Calculator is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Computes the z-score (standard score) for a given value relative to a distribution defined by mean and standard deviation

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 z-score-calculator-7c1075fd -d '<json body>'
```

Example prompt: What is the z-score for a value of 85, given a mean of 70 and a standard deviation of 10?

## When to prefer this

Use this endpoint when you need a quick, on-demand z-score computation without setting up local statistical libraries. Ideal for lightweight agent workflows that need to standardize individual data points, flag outliers, or compare values across different distributions in real time.

## Known failure modes

- Standard deviation of zero causes division-by-zero error
- Missing required fields (mean, value, std_dev) may return an error or null result
- Non-numeric inputs may cause a processing failure
- Extremely large or small numbers may produce precision issues

## Output

Returns a JSON object with a 'result' field containing the computed z-score and a 'status' field indicating success. The z-score represents how many standard deviations the input value lies above or below the mean.
