# Duplicate Observations — Record Quality Audit + Base-100 Series

> Duplicate Observations — Record Quality Audit + Base-100 Series 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 to produce a record quality audit report and a Base-100 indexed series, covering up to 200 rows in two independent analytical reports.

## 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-base-100-series-6682a724 -d '<json body>'
```

Example prompt: Run a record quality audit and Base-100 index series on my duplicate observations data — I have rows for group-a and group-b from 2026-10-01 to 2026-10-04 with duplicate_rows and total_rows filled in, using duplicate_rows as the field and row 0 as the base index.

## When to prefer this

Choose this endpoint when you have pre-collected duplicate observation records (with duplicate_rows and total_rows columns) and need both a structured data quality audit AND a Base-100 normalized trend series in a single low-cost call. It is ideal for offline/batch analytical workflows where no live data lookup or external prediction is required, and when you want two complementary views (absolute quality audit + relative index) from the same dataset in one round trip.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) on any row — validation error
- base_index out of range (0–199) or beyond submitted row count — error
- null values in duplicate_rows or total_rows may affect index computation
- Missing required fields (row_id, dataset_group, date, duplicate_rows, total_rows) — validation error
- Payment failure via x402 protocol — endpoint inaccessible

## How this service works

Duplicate observations — Record quality audit + Base-100 series: Record quality audit + Base-100 series 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) a record quality audit summarizing duplication rates, anomalies, and group-level statistics across the supplied rows; and (2) a Base-100 indexed series for the chosen field (duplicate_rows or total_rows), normalized relative to the specified base row. Both reports are computed locally from the supplied data with no external lookups.
