# JSON Outlier Detector (IQR)

> JSON Outlier Detector (IQR) is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Detects statistical outliers in a numeric array using the Interquartile Range (IQR) method

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 json-outlier-detector-iqr-66ea97ea -d '<json body>'
```

Example prompt: Can you check this list of numbers for outliers using IQR: [12, 14, 13, 100, 15, 11, 14, 200, 13]? I want to know which values are statistically anomalous.

## When to prefer this

Choose this endpoint when you need a lightweight, stateless IQR-based outlier detection computation over a simple numeric array without setting up a full data science environment. It is well-suited for quick data cleaning, sensor validation, or pre-processing steps in an agent workflow where paying per-call is acceptable and no local statistics library is available.

## Known failure modes

- Empty or missing 'values' array returns an error
- Non-numeric values in array may cause processing failure
- Extremely small arrays (fewer than 4 values) may produce unreliable IQR results
- Malformed JSON body returns a 400-level error
- Very large arrays may increase latency

## Output

Returns a JSON object with a 'result' field indicating processing outcome and a 'status' field ('success' or error). Likely also contains identified outlier positions or values within the numeric array, though the full response schema is minimal.
