# KiHustle JSON Covariance Matrix

> KiHustle JSON Covariance Matrix 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 a JSON covariance matrix from one or more input datasets

## Facts

- Endpoint: POST https://kihustle.tech/api/v1/json-covariance-matrix?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10

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-json-covariance-matrix-a11031e6 -d '<json body>'
```

Example prompt: Can you compute a covariance matrix for my dataset with variables X, Y, and Z using this endpoint — I'll pass the observations as a JSON object?

## When to prefer this

Use this endpoint when you need a quick, paid API call to compute a JSON covariance matrix from structured numeric datasets without setting up your own statistical computing environment. Best suited for lightweight on-demand covariance computation in automated pipelines.

## Known failure modes

- Missing or empty datasets object returns an error
- Non-numeric data values in datasets cause computation failure
- Malformed JSON input schema leads to a 400-level error
- Mismatched dataset dimensions (unequal observation counts per variable) may produce errors or unexpected results

## Output

Returns a JSON object containing the computed covariance matrix result with a 'result' field and a 'status' field indicating success or failure of the computation.
