# Dataset Storage Analytics — Numeric Distribution + Keyed Dataset Comparison

> Dataset Storage Analytics — Numeric Distribution + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes numeric distribution statistics and a keyed dataset comparison for two sets of dataset storage records (used_mb or row_count), returning two analytical reports for up to 200 rows each.

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-storage-analytics-numeric-distribution-keyed-dataset-comparison-c8c52b36 -d '<json body>'
```

Example prompt: Can you run a numeric distribution and keyed comparison on these two sets of dataset storage records — analyzing the used_mb field — I'll supply two arrays of up to 200 rows each with row_id, dataset_group, date, used_mb, and row_count?

## When to prefer this

Choose this endpoint when you have pre-collected dataset storage records (with used_mb and row_count fields) and need both a numeric distribution summary and a keyed row-by-row comparison between two datasets in a single $0.01 call. It is ideal for data engineers or analytics agents auditing storage growth or comparing two time-period snapshots without needing a live database connection or external data enrichment.

## Known failure modes

- Input rows array empty or missing — returns validation error
- More than 200 rows supplied — rejected with max-items error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Field value other than 'used_mb' or 'row_count' specified — enum rejection
- Null values in the selected numeric field may reduce statistical accuracy
- Row IDs not matching between 'rows' and 'other' arrays results in sparse or empty comparison report

## How this service works

Dataset storage — Numeric distribution + Keyed dataset comparison: Numeric distribution + Keyed dataset comparison for supplied dataset storage records (used_mb, row_count). 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 numeric distribution report showing statistical spread (e.g. min, max, mean, median, percentiles, histogram buckets) for the selected field (used_mb or row_count) across the supplied rows; and (2) a keyed dataset comparison report matching records from the two input arrays by row_id and reporting differences in the selected metric. All analysis is performed locally on the supplied data with no external lookups.
