# Label Review Analytics: Numeric Row Ordering + Equal-Width Histogram

> Label Review Analytics: Numeric Row Ordering + 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 2026-10-23).

Generates two analytical reports — numeric row ordering and an equal-width histogram — for label review data (reviewed_records and changed_labels) across up to 200 rows.

## 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-equal-width-histogram-d3e4ca69 -d '<json body>'
```

Example prompt: I have label review data for 4 dataset groups — can you generate a numeric row ordering report and a 5-bin equal-width histogram on the reviewed_records field? Here are the 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 fast, self-contained numeric ordering and histogram analysis on label review data (reviewed_records or changed_labels) without any external data lookup or ML prediction. Ideal for auditing label correction volumes, understanding workload distribution across dataset groups, or generating summary statistics on up to 200 label review records for a fixed low cost of $0.01 USDC for both reports together.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row validation failure
- bins parameter out of range (must be 1–30) causes error
- Null values in the target field may be excluded or cause incomplete histogram bins
- Missing required fields (row_id, dataset_group, date, reviewed_records, changed_labels) cause row rejection

## How this service works

Label review — Numeric row ordering + Equal-width histogram: Numeric row ordering + Equal-width histogram 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

Two analytical reports computed locally from the supplied data: (1) a numeric row ordering that ranks the provided rows by the chosen field (reviewed_records or changed_labels), and (2) an equal-width histogram with the specified number of bins showing frequency distribution of the same field across the input rows. No external lookups or predictions are made.
