# KiHustle Paired T-Test

> KiHustle Paired T-Test is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-13).

Performs a paired (dependent samples) t-test on two numeric arrays to determine statistical significance of the difference between before and after measurements

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-paired-t-test-2f29b88a -d '<json body>'
```

Example prompt: Run a paired t-test on my before and after measurements — before: [12.1, 13.4, 11.8, 14.2, 12.9] and after: [13.5, 14.1, 12.7, 15.0, 13.8] — and tell me if the difference is statistically significant.

## When to prefer this

Choose this endpoint when you have paired or repeated-measures data (the same subjects measured before and after an intervention or under two conditions) and need to test whether the mean difference is statistically significant. It is specifically suited for dependent samples rather than independent groups.

## Known failure modes

- Arrays of unequal length — paired t-test requires matched pairs so mismatched array sizes will cause an error
- Empty arrays provided for before or after
- Non-numeric values in the input arrays
- Single-element arrays insufficient for variance calculation
- Network timeout or payment authorization failure

## Output

Returns a JSON object indicating whether the paired t-test was processed successfully, with a 'result' field confirming processing and a 'status' field showing success or failure. Detailed t-statistic, p-value, and significance findings are expected in the result payload.
