# Process Handoffs — Two-Measure Correlation + Secondary-Measure Weighted Mean

> Process Handoffs — Two-Measure Correlation + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Computes Pearson correlation between handoff_count and wait_minutes, plus a weighted mean for a chosen secondary measure, across up to 200 process handoff records.

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 process-handoffs-two-measure-correlation-secondary-measure-weighted-0e289677 -d '<json body>'
```

Example prompt: Can you run a correlation and weighted mean analysis on these process handoff records — I have up to 200 rows with handoff_count and wait_minutes fields per team group, and I want to use handoff_count as the primary field?

## When to prefer this

Choose this endpoint when you have structured process handoff records (handoff_count, wait_minutes per row) and need both a pairwise correlation and a weighted mean in a single low-cost call ($0.01 USDC for 2 reports). Prefer it over generic analytics tools when your dataset fits within 200 rows and you want a lightweight, no-external-dependency statistical summary without prediction or professional assessment.

## Known failure modes

- Fewer than 1 row supplied — validation error
- More than 200 rows submitted — rejected with max-items error
- Missing required fields (row_id, date, handoff_count, wait_minutes) in any row — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Non-numeric values in handoff_count or wait_minutes where numbers are expected — type error
- Payment not processed — x402 payment required response

## How this service works

Process handoffs — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied process handoffs records (handoff_count, wait_minutes). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two analytical reports: (1) a Pearson correlation coefficient between handoff_count and wait_minutes across the supplied rows, and (2) a weighted mean for the selected secondary measure (handoff_count or wait_minutes). Both are computed locally using shared analytical engines on up to 200 supplied data rows with no external lookups.
