# Duplicate Observations IQR Outlier Flags and Keyed Dataset Comparison

> Duplicate Observations IQR Outlier Flags and 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 2026-10-20).

Runs two local analytical reports on duplicate-observation records: IQR-based outlier detection and a keyed comparison between two supplied 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-iqr-outlier-flags-and-keyed-dataset-comparison-e053dcb4 -d '<json body>'
```

Example prompt: Can you run IQR outlier flagging and a keyed dataset comparison on my duplicate observation data? I have two sets of up to 50 rows each with duplicate_rows and total_rows counts per group, and I want to analyze the duplicate_rows field.

## When to prefer this

Choose this endpoint when you have pre-collected duplicate observation records (up to 200 rows) and need both IQR-based outlier detection and a keyed cross-dataset comparison in a single call. It is best suited for data quality workflows, ETL monitoring, and dataset auditing where you supply your own data and need local statistical analysis without external lookups or predictions. Prefer it over single-report endpoints when you need both outlier flags and a comparison simultaneously at a low cost ($0.01 USDC for both reports).

## Known failure modes

- Fewer than 1 row provided — validation error
- More than 200 rows submitted — rejected, maxItems limit exceeded
- Missing required fields (row_id, dataset_group, date, duplicate_rows, total_rows) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Non-numeric values in duplicate_rows or total_rows — type error
- Insufficient data variance for meaningful IQR computation — may return degenerate outlier results
- Payment not included or insufficient — x402 payment required error

## How this service works

Duplicate observations — IQR outlier flags + Keyed dataset comparison: IQR outlier flags + 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) IQR outlier flags identifying which rows have duplicate_rows or total_rows values outside the interquartile range, and (2) a keyed dataset comparison highlighting differences between the primary and secondary supplied datasets, matched by row_id. All computation is performed locally with no external lookups.
