## 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 purchase-orders-exact-row-deduplication-two-measure-correlation-fcf6ef64 -d '<json body>'
```

Example prompt: Can you deduplicate my purchase order records and compute the correlation between ordered_amount and received_amount? I have rows with row_id, store_group, date, ordered_amount, and received_amount — here are up to 200 rows from my retail dataset.

## When to prefer this

Choose this endpoint when you have purchase order tabular data (up to 200 rows) and need both exact row deduplication and a two-measure correlation analysis in a single low-cost call ($0.01 USDC). It is ideal for offline/batch data quality checks on retail purchase order datasets where no live lookups, external data enrichment, or predictions are required.

## Known failure modes

- Exceeds 200 row limit — request rejected or truncated
- Missing required fields (row_id, date, ordered_amount, received_amount) — validation error
- Invalid date format (must be YYYY-MM-DD) — schema validation failure
- All rows are duplicates — deduplication report returns empty or single-row result
- Null values in both measure columns — correlation undefined or NaN
- Insufficient variance in measures — correlation computation returns warning

## How this service works

Purchase orders — Exact row deduplication + Two-measure correlation: Exact row deduplication + Two-measure correlation for supplied purchase orders records (ordered_amount, received_amount). 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 deduplication report identifying and removing exact duplicate rows from the submitted purchase order records, and (2) a Pearson or equivalent correlation report quantifying the statistical relationship between ordered_amount and received_amount across the cleaned dataset.
