## 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 label-review-analytics-date-by-category-pivot-keyed-dataset-comparison-f7180abb -d '<json body>'
```

Example prompt: Run a date-by-category pivot and keyed dataset comparison on my label review data — primary dataset has rows like {row_id: 'row-1', dataset_group: 'group-a', date: '2026-10-01', reviewed_records: 10, changed_labels: 1} (up to 200 rows), and I want to compare it against a second dataset with the same structure, analyzing the 'reviewed_records' field.

## When to prefer this

Choose this endpoint when you have label review or annotation data organized by date and dataset group and need both a pivot summary and a side-by-side dataset comparison in a single cheap call ($0.01 USDC). It is ideal for ML data ops, annotation auditing, or quality assurance workflows where you want to compare two batches of up to 200 rows without any external lookups or live model inference.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, dataset_group, date, reviewed_records, changed_labels) — validation error
- Invalid date format (must match YYYY-MM-DD) — schema rejection
- Numeric values outside allowed range (-1e12 to 1e12) — validation error
- Empty rows array — minimum 1 item required
- Field enum value not 'reviewed_records' or 'changed_labels' — rejected

## How this service works

Label review — Date by category pivot + Keyed dataset comparison: Date by category pivot + Keyed dataset comparison for supplied label review records (reviewed_records, changed_labels). 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 independent analytical reports: (1) a date-by-category pivot table cross-tabulating the chosen field (reviewed_records or changed_labels) across dates and dataset_group values, and (2) a keyed dataset comparison highlighting row-level or aggregate differences between the primary and secondary supplied datasets. All computation is local with no external lookups.
