## 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-daily-sum-series-date-by-category-pivot-f127f513 -d '<json body>'
```

Example prompt: Can you run a daily sum series and date-by-category pivot on my label review data? I have rows with dates, dataset groups like 'group-a' and 'group-b', and I want to analyze the reviewed_records field — here are up to 200 rows to process.

## When to prefer this

Choose this endpoint when you have label review tabular data (up to 200 rows) and need both a daily sum time series and a date-by-category pivot in a single low-cost call ($0.01 USDC). Ideal for ML data labeling pipelines, annotation quality audits, or any scenario where reviewed_records or changed_labels must be aggregated by day and group without external lookups or predictions.

## Known failure modes

- Input array empty or missing — minimum 1 row required
- More than 200 rows submitted — maxItems limit exceeded
- Invalid date format — must match YYYY-MM-DD pattern
- Missing required fields (row_id, date, dataset_group) on any row
- Numeric values out of allowed range (±1,000,000,000,000)
- Invalid field enum value — must be 'reviewed_records' or 'changed_labels'
- Payment failure — 0.01 USDC required per call

## How this service works

Label review — Daily sum series + Date by category pivot: Daily sum series + Date by category pivot 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 computed locally from the supplied data: (1) a daily sum time series showing aggregated values of the selected field (reviewed_records or changed_labels) per date, and (2) a date-by-category pivot table breaking down totals by date and dataset_group. No external data is fetched or predicted.
