# KiHustle Z-Score Calculator

> KiHustle 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 2026-09-14).

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

## Facts

- Endpoint: POST https://kihustle.tech/nexus/api/v1/z-score-calculator
- Price: $0.002/call
- Payment: x402
- Status: unknown

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-z-score-calculator-a49567d4 -d '<json body>'
```

Example prompt: Calculate the z-score for a value of 85, where the mean is 70 and the standard deviation is 10.

## When to prefer this

Use this endpoint when you need a quick, stateless Z-score computation without setting up local math libraries. Suitable for lightweight statistical normalization tasks in automated pipelines where a remote computation call is acceptable. If you are computing many Z-scores in batch or have local math capabilities, computing locally is more efficient.

## Known failure modes

- Missing required fields (value, mean, std_dev) result in an error response
- Standard deviation of zero causes division-by-zero error
- Non-numeric inputs may return a validation error
- Malformed JSON body may result in a 400-level error

## Output

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