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-correlation-calculator-ffe3a6cf -d '<json body>'
```

Example prompt: Can you calculate the Pearson correlation between these two series? series_a is [1, 2, 3, 4, 5] and series_b is [2.1, 3.9, 6.2, 8.0, 9.8].

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002) Pearson correlation coefficient computed server-side from two numeric arrays, particularly in automated pipelines or agents where you want to avoid local statistical libraries. Suitable for moderate-sized datasets where real-time computation is needed.

## Known failure modes

- Mismatched array lengths between series_a and series_b may cause an error or undefined result
- Empty arrays or arrays with a single element cannot produce a valid correlation
- Non-numeric values in either series will likely cause a processing failure
- Zero-variance series (all identical values) will result in undefined correlation (division by zero)
