# Returns Handling Analytics — Two-Measure Correlation + Secondary-Measure Weighted Mean

> Returns Handling Analytics — 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 2026-11-02).

Computes Pearson correlation between returned_units and processing_minutes, plus a weighted mean of the secondary measure, for up to 200 rows of returns handling data.

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 returns-handling-analytics-two-measure-correlation-secondary-measure-65a60ba9 -d '<json body>'
```

Example prompt: Run a two-measure correlation and weighted mean analysis on my returns handling data — here are 4 rows with returned_units and processing_minutes across store groups group-a and group-b from October 2026 — use returned_units as the primary field.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) statistical summary — specifically a two-measure correlation and weighted mean — for retail returns handling records (up to 200 rows) without requiring external data access, predictions, or professional assessments. Ideal for ops teams validating whether return volume correlates with processing time and wanting a weighted average in a single API call.

## Known failure modes

- Fewer than 1 row supplied — validation error
- More than 200 rows supplied — request rejected
- Missing required fields (row_id, date, returned_units, processing_minutes) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Null values in both measures may reduce correlation reliability
- Insufficient variance in data may produce undefined or degenerate correlation

## How this service works

Returns handling — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + Secondary-measure weighted mean for supplied returns handling records (returned_units, processing_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 or comparable correlation coefficient between returned_units and processing_minutes across the supplied rows, and (2) a weighted mean of the secondary measure. Results are computed locally from the supplied data only, with no external lookups or predictions.
