- Price: $0.002/call
- Payment: x402
- Status: unknown

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-pearson-json-correlation-35fd30c8 -d '<json body>'
```

Example prompt: Calculate the Pearson correlation coefficient for these two datasets: [2.1, 3.4, 5.6, 7.8, 9.0] and [1.9, 3.1, 5.2, 7.5, 8.8] — I want to know how strongly they're linearly related.

## When to prefer this

Use this endpoint when you need a fast, pay-per-call Pearson correlation computation over two numeric datasets formatted as JSON, without setting up a local statistics library or running your own compute infrastructure.

## Known failure modes

- Invalid or malformed JSON input returns an error response
- Non-numeric values in dataset arrays cause computation failure
- Mismatched array lengths between the two datasets
- Empty arrays or single-element arrays cannot produce a valid correlation
- Network timeout for very large datasets
