# Dataset Storage Analytics — Numeric Row Ordering + Keyed Dataset Comparison

> Dataset Storage Analytics — Numeric Row Ordering + 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 2026-10-19).

Ranks dataset storage rows by a chosen numeric field (used_mb or row_count) and compares two datasets by shared key, returning two analytical reports for up to 200 rows.

## 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-row-ordering-keyed-dataset-comparison-b678030d -d '<json body>'
```

Example prompt: I have two snapshots of my dataset storage table — each up to 200 rows with columns row_id, dataset_group, date, used_mb, and row_count — can you rank the rows by used_mb and also compare the two snapshots side-by-side by row_id?

## When to prefer this

Choose this endpoint when you need both a ranked ordering of dataset storage records by a numeric field AND a keyed comparison between two dataset snapshots in a single paid call. It is purpose-built for storage metadata (used_mb, row_count) and operates entirely on supplied data with no external lookups, making it suitable for offline or batch audit workflows where you have two versions of a dataset table and want to surface rank order and row-level deltas simultaneously.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, dataset_group, date, used_mb, row_count) on any row — validation error
- Invalid date format (must be YYYY-MM-DD) — schema validation failure
- Field selector not one of 'used_mb' or 'row_count' — enum validation error
- Empty rows array (minItems: 1 violated) — request rejected
- Payment of 0.01 USDC not provided or insufficient — 402 payment required

## How this service works

Dataset storage — Numeric row ordering + Keyed dataset comparison: Numeric row ordering + 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 ordering of the submitted rows ranked by the selected field (used_mb or row_count), and (2) a keyed comparison between the primary and secondary datasets aligned by row_id, highlighting additions, removals, and value differences — all computed locally without external lookups.
