# Duplicate Observations Analytics — Numeric Row Ordering + IQR Outlier Flags

> Duplicate Observations Analytics — Numeric Row Ordering + IQR Outlier Flags 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).

Analyzes supplied duplicate-observation records (duplicate_rows, total_rows) to produce numeric row ordering and IQR-based outlier flag reports, up to 200 rows, with two independent analytical reports per call.

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-numeric-row-ordering-iqr-outlier-flags-11df0fba -d '<json body>'
```

Example prompt: Can you analyze these dataset duplicate-row records and give me both a numeric row ordering and IQR outlier flags for the duplicate_rows field? I have 4 records: row-1 on 2026-10-01 in group-a with 10 duplicate_rows out of 1 total, row-2 on 2026-10-02 in group-b with 20 duplicate_rows out of 2 total, row-3 on 2026-10-03 in group-a with 15 duplicate_rows out of 3 total, and row-4 on 2026-10-04 in group-b with 30 duplicate_rows out of 4 total.

## When to prefer this

Choose this endpoint when you have structured duplicate-observation records with row-level duplicate_rows and total_rows counts and need both ranked ordering and IQR-based outlier detection in a single call. It is ideal for lightweight, local data quality audits of up to 200 rows where no external data access, prediction, or live lookup is required. At $0.01 USDC for two reports, it is cost-effective for batch data quality checks on ETL outputs, dataset merges, or periodic data audits.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — request rejected
- Missing required fields (row_id, dataset_group, date, duplicate_rows, total_rows) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in both numeric fields may reduce IQR calculation accuracy
- row_id or dataset_group exceeding 80 characters — validation error
- Field enum value other than 'duplicate_rows' or 'total_rows' — rejection

## How this service works

Duplicate observations — Numeric row ordering + IQR outlier flags: Numeric row ordering + IQR outlier flags 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 per call: (1) numeric row ordering of the submitted records ranked by the selected field (duplicate_rows or total_rows), and (2) IQR-based outlier flags identifying which rows fall outside the interquartile range. No external data is fetched; all analysis is performed locally on the supplied data.
