# 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 2026-10-22).

Computes a JSON-formatted covariance matrix from one or more input datasets

## Facts

- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22

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-01f1a222 -d '<json body>'
```

Example prompt: Can you compute a covariance matrix for my datasets — I have three variables: returns for assets A, B, and C over 10 periods — and return the result as JSON?

## When to prefer this

Choose this endpoint when you need a quick, paid, stateless covariance matrix computation returned as structured JSON without setting up your own statistical library or compute environment. Best suited for lightweight, on-demand statistical analysis within an agent workflow where you pass datasets and immediately receive the matrix result.

## Known failure modes

- Missing or malformed datasets object returns an error
- Non-numeric data in datasets causes computation failure
- Empty dataset object may return a trivial or error result
- Insufficient data points per variable may yield unreliable covariance estimates
- Network or payment processing errors return a 402 or 5xx response

## Output

Returns a JSON object containing the computed covariance matrix across the provided datasets, along with a status field indicating success. The matrix captures pairwise covariances between all variables supplied in the input.
