## 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-exact-row-deduplication-two-measure-correlation-ebccf11d -d '<json body>'
```

Example prompt: Can you deduplicate my returns handling records and compute the correlation between returned_units and processing_minutes? I have about 150 rows across several store groups from October 2026.

## When to prefer this

Choose this endpoint when you need both exact-row deduplication and a two-measure correlation analysis on returns handling data (returned_units vs processing_minutes) in a single low-cost call. Ideal for retail operations analysts who want to clean their dataset and measure KPI relationships simultaneously without building custom analytical pipelines. Best for datasets of up to 200 rows where no live data lookup or predictive modeling is needed.

## Known failure modes

- Input exceeds 200 rows — request rejected
- Missing required fields (row_id, date, returned_units, processing_minutes) — validation error
- Date format not matching YYYY-MM-DD pattern — schema validation failure
- All rows are duplicates leaving insufficient data for correlation — edge case result
- Null values in both measure columns preventing correlation computation

## How this service works

Returns handling — Exact row deduplication + Two-measure correlation: Exact row deduplication + Two-measure correlation 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) an exact row deduplication report identifying duplicate records in the input dataset, and (2) a two-measure correlation report quantifying the statistical relationship between returned_units and processing_minutes across all submitted rows.
