# Label Review Analytics — Numeric Row Ordering & Keyed Dataset Comparison

> Label Review 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 2026-10-15).

Analyzes label review records by sorting rows numerically and comparing two keyed datasets to surface differences in reviewed_records and changed_labels metrics.

## 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-numeric-row-ordering-keyed-dataset-comparison-dede0e79 -d '<json body>'
```

Example prompt: I have two batches of label review data — the original and a revised version — each with up to 50 rows containing row_id, dataset_group, date, reviewed_records, and changed_labels. Can you rank both datasets numerically by reviewed_records and compare them keyed by row_id to show me where the values differ?

## When to prefer this

Choose this endpoint when you need both a ranked ordering of label review rows and a keyed side-by-side comparison of two label review datasets in a single API call. It is ideal for annotation quality audits, label drift detection between review rounds, and comparing dataset groups — all without any external data lookup or model inference. At $0.01 USDC for two reports covering up to 200 rows, it is cost-effective for batch label review analytics pipelines.

## Known failure modes

- Missing required fields (row_id, dataset_group, date, reviewed_records, or changed_labels) causes validation error
- Exceeding 200 rows in either array returns a schema validation failure
- Invalid date format (not YYYY-MM-DD) triggers pattern mismatch error
- Numeric values outside allowed range (±1,000,000,000,000) are rejected
- Empty rows array (minItems: 1 not met) returns an error
- Invalid field enum value (anything other than reviewed_records or changed_labels) causes rejection

## How this service works

Label review — Numeric row ordering + Keyed dataset comparison: Numeric row ordering + 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 numeric row ordering report that ranks the submitted rows by the selected field (reviewed_records or changed_labels), and (2) a keyed dataset comparison report that matches rows from the primary and secondary datasets by row_id and highlights value differences — all computed locally with no external lookups.
