# Label Review — Adjacent Row Changes + Keyed Dataset Comparison

> Label Review — Adjacent Row Changes + 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).

Runs two analytical reports on label review data: detects adjacent row changes and performs a keyed dataset comparison, for up to 200 rows per call.

## 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-adjacent-row-changes-keyed-dataset-comparison-f1de01cd -d '<json body>'
```

Example prompt: Can you run adjacent row change detection and a keyed dataset comparison on my label review records? I have two datasets — my current batch and a baseline — each up to 50 rows with reviewed_records and changed_labels per date and dataset_group, and I want to compare on the reviewed_records field.

## When to prefer this

Choose this endpoint when you need to analyze label review data specifically — tracking how reviewed_records or changed_labels evolve across sequential rows and/or comparing two keyed label review datasets for discrepancies. It is ideal when you want two bundled analytical reports (adjacent changes + keyed comparison) in a single low-cost call without any external API dependency. Prefer alternatives if you need IQR outlier detection, histogram analysis, or data types outside label review (e.g. pipeline durations, procurement research).

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, dataset_group, date, reviewed_records, changed_labels) — validation error
- Date field does not match YYYY-MM-DD pattern — schema error
- field enum value not one of 'reviewed_records' or 'changed_labels' — rejected
- Primary or reference dataset empty (minItems:1 violated) — error
- Numeric values outside allowed range (±1,000,000,000,000) — schema error

## How this service works

Label review — Adjacent row changes + Keyed dataset comparison: Adjacent row changes + 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) an adjacent row changes report showing how reviewed_records or changed_labels values shift between consecutive rows, including deltas and change magnitudes; and (2) a keyed dataset comparison report matching rows from the primary and reference datasets by key, highlighting differences in the selected metric. No external lookups or predictions are made — all analysis is computed locally from the supplied data.
