## 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 recruitment-funnel-two-measure-correlation-1c10f810 -d '<json body>'
```

Example prompt: Can you calculate the correlation between applications and interviews for my recruitment funnel data? I have 4 records: group-a on 2026-10-01 with 10 applications and 1 interview, group-b on 2026-10-02 with 20 applications and 2 interviews, group-a on 2026-10-03 with 15 applications and 3 interviews, and group-b on 2026-10-04 with 30 applications and 4 interviews.

## When to prefer this

Choose this endpoint when you need a fast, local statistical correlation between exactly two numeric recruitment funnel measures (applications and interviews) on up to 200 typed records, without needing external data enrichment, forecasting, or more than two variables. It is ideal for lightweight HR analytics pipelines where cost, speed, and simplicity matter.

## Known failure modes

- Fewer than 1 row submitted — rejected by minItems constraint
- More than 200 rows submitted — rejected by maxItems constraint
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Both measure fields null for all rows — insufficient numeric data for correlation
- Constant values in one or both measures — correlation undefined or returns NaN
- Missing required fields (row_id, source, date, applications, interviews) — schema rejection
