# Duplicate Observations Analytics — Equal-Width Histogram & Keyed Dataset Comparison

> Duplicate Observations Analytics — Equal-Width Histogram & 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 2026-10-18).

Runs two local analytical reports on duplicate-observation records: an equal-width histogram of a chosen field and a keyed side-by-side comparison of two datasets, for up to 200 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 duplicate-observations-analytics-equal-width-histogram-keyed-dataset-94837891 -d '<json body>'
```

Example prompt: Can you analyze my duplicate observation records and give me both a 10-bin equal-width histogram of the duplicate_rows field and a keyed comparison between my group-a and group-b datasets? I'll supply up to 50 rows for each.

## When to prefer this

Choose this endpoint when you need to understand the distribution of duplicate row counts across a dataset (histogram) and simultaneously compare two versions or groups of the same dataset side-by-side (keyed comparison). It is ideal for data quality workflows, deduplication audits, and before/after dataset comparisons where both frequency distribution insight and record-level diff are needed together in one call at low cost. Not suitable for live data lookup, prediction, or external data enrichment.

## Known failure modes

- Exceeds 200-row limit — request rejected
- Missing required fields (row_id, dataset_group, date, duplicate_rows, total_rows) — validation error
- Invalid date format (must match YYYY-MM-DD) — schema validation failure
- bins parameter out of range (must be 1–30) — error
- Empty rows array — rejected by minItems constraint
- Null values in numeric fields may affect histogram binning accuracy

## How this service works

Duplicate observations — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison for supplied duplicate observations records (duplicate_rows, total_rows). 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) an equal-width histogram dividing the chosen field (duplicate_rows or total_rows) into the specified number of bins with counts per bin, and (2) a keyed dataset comparison report highlighting differences between the primary and secondary dataset records matched by row_id, dataset_group, and date.
