# Dataset Partition Sizes — Date×Category Pivot + Missing-Value Fill

> Dataset Partition Sizes — Date×Category Pivot + Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Produces two analytical reports from dataset partition records: a date-by-category pivot table and an explicit missing-value fill, for up to 200 rows of row_count or file_mb 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 dataset-partition-sizes-date-category-pivot-missing-value-fill-ae9e4a4e -d '<json body>'
```

Example prompt: I have partition size records for a few dataset groups across dates in October 2026 — can you pivot the row_count values by date and category, and fill any missing values using median?

## When to prefer this

Choose this endpoint when you have up to 200 dataset partition records (with row_count or file_mb metrics) and need both a date×category pivot and explicit missing-value imputation in a single low-cost call. It is ideal for data engineering pipelines that need to inspect partition distributions over time across dataset groups, without requiring a live database or external analytics service.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, dataset_group, date, row_count, file_mb) on any row — validation error
- Date strings not matching YYYY-MM-DD pattern — schema rejection
- Numeric values outside allowed range — validation error
- Empty rows array — schema rejection

## How this service works

Dataset partition sizes — Date by category pivot + Explicit missing-value fill: Date by category pivot + Explicit missing-value fill for supplied dataset partition sizes records (row_count, file_mb). 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

Two analytical reports: (1) a pivot table with dates as rows and dataset_group values as columns, showing the selected metric (row_count or file_mb); (2) the same records with missing values explicitly filled using the chosen method (zero, mean, or median). Both computed locally without external data.
