# Label Review Analytics: Record Quality Audit + Deduplication + Equal-Width Histogram

> Label Review Analytics: Record Quality Audit + Deduplication + Equal-Width Histogram 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 three local analytical reports on label review data: a record quality audit, exact row deduplication, and an equal-width histogram — all computed offline against up to 200 supplied rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-record-quality-audit-deduplication-equal-width-ac4ddf43 -d '<json body>'
```

Example prompt: Run a quality audit, exact deduplication check, and a 5-bin histogram on the reviewed_records column for my label review dataset — here are 4 rows: row-1 group-a 2026-10-01 reviewed=10 changed=1, row-2 group-b 2026-10-02 reviewed=20 changed=2, row-3 group-a 2026-10-03 reviewed=15 changed=3, row-4 group-b 2026-10-04 reviewed=30 changed=4.

## When to prefer this

Choose this endpoint when you need a fast, offline, combined data profiling pass — quality audit, deduplication, and histogram — on label review data with up to 200 rows. It is ideal for ML annotation pipelines where you want to validate data before training without making any external API calls or incurring additional per-report costs. At $0.01 USDC for three reports, it is cost-efficient for batch pre-flight checks on small-to-medium label review exports.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, dataset_group, date, reviewed_records, changed_labels) will cause row-level errors
- Invalid date format (not YYYY-MM-DD) will fail schema validation
- Bins value outside 1–30 range will be rejected
- Numeric values outside ±1,000,000,000,000 will fail validation
- Empty rows array (minItems: 1) will be rejected
- Payment not included or insufficient USDC will result in 402 response

## How this service works

Label review — Record quality audit + Exact row deduplication + Equal-width histogram: Record quality audit + Exact row deduplication + Equal-width histogram for supplied label review records (reviewed_records, changed_labels). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent analytical reports computed locally against the supplied rows: (1) a record quality audit flagging null values, out-of-range fields, and format violations; (2) an exact row deduplication report identifying and counting duplicate rows; (3) an equal-width histogram for the selected numeric field (reviewed_records or changed_labels) across the specified number of bins. No external lookups or predictions are made.
