# KiHustle Linear Regression Predict

> KiHustle Linear Regression Predict 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).

Fits a linear regression model to a set of (x, y) data points and returns a predicted y-value for a given x input.

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-linear-regression-predict-fa57f94b -d '<json body>'
```

Example prompt: I have these data points — (1, 2), (2, 4), (3, 5.5), (4, 8) — can you fit a linear regression to them and predict the y value when x is 6?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call linear regression prediction without setting up a local ML environment. It is ideal for simple trend extrapolation on small numeric datasets where a straight-line model is appropriate. Prefer alternatives if you need polynomial regression, multivariate inputs, confidence intervals, or model coefficients rather than just a point prediction.

## Known failure modes

- Insufficient data points (fewer than 2) causing inability to fit a line
- Non-numeric values in the points array causing schema validation failure
- Missing 'predict_x' field returning an error or null result
- Collinear or identical x-values causing a degenerate regression (division by zero)
- Malformed points objects (missing x or y keys) leading to processing errors

## Output

Returns a JSON object with a 'result' field containing the predicted y-value for the given x input, along with a 'status' field confirming success. The prediction is derived from a linear model fit to the provided data points.
