# Duplicate Observations — Record Quality Audit + Secondary-Measure Weighted Mean

> Duplicate Observations — Record Quality Audit + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Runs two local analytical reports on supplied duplicate-observation records: a record quality audit and a secondary-measure weighted mean, for 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 duplicate-observations-record-quality-audit-secondary-measure-071a8d6d -d '<json body>'
```

Example prompt: Can you run a record quality audit and a weighted mean report on my duplicate observations data? I have 4 rows — row-1 (group-a, 2026-10-01, 10 duplicate_rows out of 1 total), row-2 (group-b, 2026-10-02, 20 out of 2), row-3 (group-a, 2026-10-03, 15 out of 3), row-4 (group-b, 2026-10-04, 30 out of 4) — and I want the weighted mean calculated on the duplicate_rows field.

## When to prefer this

Choose this endpoint when you need two simultaneous analytical reports — a record quality audit and a weighted mean — on a batch of up to 200 duplicate-observation records, entirely from supplied data with no external lookups. It is ideal for data quality pipelines, deduplication monitoring workflows, and dataset integrity audits where you already have the duplicate_rows and total_rows counts and want structured statistical summaries at low cost ($0.01 USDC for both reports).

## Known failure modes

- Input array is empty or exceeds 200 rows — rejected with validation error
- Required fields (row_id, dataset_group, date, duplicate_rows, total_rows) missing from any row — schema validation failure
- Date field does not match YYYY-MM-DD format — pattern validation error
- Numeric fields out of supported range (±1,000,000,000,000) — validation rejection
- Invalid field enum value (not 'duplicate_rows' or 'total_rows') — rejected
- Payment not provided or insufficient — x402 payment required response

## How this service works

Duplicate observations — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean 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

Two analytical reports generated locally: (1) a record quality audit assessing the supplied duplicate observation rows for quality issues such as anomalous ratios or missing values, and (2) a weighted mean computation on the selected field (duplicate_rows or total_rows) across the supplied rows, grouped as appropriate. No external data is fetched; all analysis is performed on the provided input rows.
