# Label Review Analytics: Numeric Distribution + Keyed Dataset Comparison

> Label Review 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 performs a keyed dataset comparison for label review records (reviewed_records, changed_labels) across up to 200 rows, returning two independent analytical reports.

## 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-distribution-keyed-dataset-comparison-e40bbb52 -d '<json body>'
```

Example prompt: I have two batches of label review records (up to 200 rows each) with reviewed_records and changed_labels columns — can you run a numeric distribution analysis on reviewed_records and also compare the two datasets row-by-row using keyed matching to see where they differ?

## When to prefer this

Choose this endpoint when you have structured label review data with reviewed_records and changed_labels fields and need both a numeric distribution summary and a keyed comparison between two datasets in a single $0.01 call. It is ideal for ML annotation pipelines, data labeling QA workflows, or auditing label correction rates across groups or time periods. Prefer it over general analytics tools when your data fits the label review schema and you want offline, deterministic computation without any external lookups or predictions.

## Known failure modes

- More than 200 rows submitted — request rejected due to row limit
- Missing required fields (row_id, dataset_group, date, reviewed_records, changed_labels) in any row — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- No 'other' dataset provided when comparison report is expected — incomplete comparison output
- Numeric values out of allowed range (beyond ±1,000,000,000,000) — validation error
- Empty rows array — minimum 1 item required

## How this service works

Label review — Numeric distribution + Keyed dataset comparison: Numeric distribution + 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 distribution report for the selected field (reviewed_records or changed_labels) across the supplied rows, including statistics such as min, max, mean, median, and spread metrics; and (2) a keyed dataset comparison report that matches rows between the primary and secondary datasets by key and highlights differences in the numeric fields.
