# Label Review Analytics: Duplicate Key Report + Keyed Dataset Comparison

> Label Review Analytics: Duplicate Key Report + 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: a duplicate key detection report and a keyed comparison between two datasets, for up to 200 rows each.

## 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-duplicate-key-report-keyed-dataset-comparison-6b16fa4b -d '<json body>'
```

Example prompt: Can you check my label review data for duplicate row keys and also compare it against last week's snapshot? I have two datasets — the primary one has rows like row-1 through row-50 across group-a and group-b with reviewed_records and changed_labels counts, and the second dataset is the earlier version I want to diff it against.

## When to prefer this

Choose this endpoint when you need to audit label review or annotation datasets for duplicate row keys and/or diff two versions of a keyed dataset without requiring external lookups or ML predictions. It is specifically designed for the reviewed_records and changed_labels schema common in data labeling workflows, handling up to 200 rows per call with two reports bundled at a flat $0.01 USDC cost. Prefer this over generic data-diff tools when your data fits the label review domain schema.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Rows missing required fields (row_id, dataset_group, date, reviewed_records, changed_labels) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Numeric values outside allowed range (±1,000,000,000,000) — validation error
- Empty rows array — minItems constraint violated
- Payment not included or insufficient — x402 payment required error

## How this service works

Label review — Duplicate key report + Keyed dataset comparison: Duplicate key report + 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 duplicate key report identifying any row_ids that appear more than once in the primary dataset, and (2) a keyed dataset comparison highlighting rows that differ, are missing, or are added between the primary and comparison datasets, based on row_id as the key.
