# Label Review Analytics: Numeric Interval Filter + Equal-Width Histogram

> Label Review Analytics: Numeric Interval Filter + 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 two analytical reports on label review records — a numeric interval filter and an equal-width histogram — for up to 200 rows of reviewed_records or changed_labels data.

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-numeric-interval-filter-equal-width-histogram-6cf6a3fe -d '<json body>'
```

Example prompt: Analyze my label review data — here are 150 rows with reviewed_records and changed_labels — filter rows where reviewed_records is between 10 and 500, and also give me an equal-width histogram of reviewed_records with 8 bins.

## When to prefer this

Choose this endpoint when you have label review records (with reviewed_records and changed_labels fields) and need both a range-filtered subset and a histogram distribution in a single API call for up to 200 rows. It is purpose-built for ML annotation QA workflows where understanding the distribution and range of label changes or review volumes is the primary goal. Prefer this over general analytics tools when working with the specific label review schema and when cost efficiency ($0.01 for two reports) matters.

## Known failure modes

- Fewer than 1 row submitted — API returns validation error
- More than 200 rows submitted — request rejected
- bins value outside 1–30 range — validation error
- field value not in enum [reviewed_records, changed_labels] — rejected
- minimum greater than maximum — may produce empty filter result or error
- Rows missing required fields (row_id, date, reviewed_records, changed_labels) — validation failure
- All values null for selected field — histogram may be empty or degenerate

## How this service works

Label review — Numeric interval filter + Equal-width histogram: Numeric interval filter + 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

Returns two independent analytical reports: (1) a numeric interval filter listing which submitted rows have the selected field (reviewed_records or changed_labels) falling within the specified minimum–maximum range, and (2) an equal-width histogram breaking the field's value range into the requested number of bins with counts per bin. Both reports operate on the supplied rows locally with no external lookups.
