# Duplicate Observations Analytics — Record Quality Audit, String Normalisation & Numeric Distribution

> Duplicate Observations Analytics — Record Quality Audit, String Normalisation & Numeric Distribution 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 three analytical reports (record quality audit, string normalisation, numeric distribution) on up to 200 duplicate-observation records containing duplicate_rows and total_rows fields.

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-record-quality-audit-string-948d0ed6 -d '<json body>'
```

Example prompt: Run the three-report analytics bundle (record quality audit, string normalisation, and numeric distribution) on my duplicate observations data — here are 4 rows: 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; focus the numeric analysis on the duplicate_rows field.

## When to prefer this

Choose this endpoint when you have up to 200 duplicate-observation records and need three complementary data quality reports in a single low-cost call ($0.01 USDC). It is ideal for auditing deduplication pipeline outputs, profiling string consistency in group labels, and understanding the numeric distribution of duplicate counts — all without any external API calls, predictions, or live lookups. Prefer it over single-report alternatives when you need the combined quality + normalisation + distribution view on the same dataset in one shot.

## Known failure modes

- More than 200 rows submitted — request rejected, maxItems limit exceeded
- Missing required fields (row_id, dataset_group, date, duplicate_rows, or total_rows) — validation error
- Date field not matching YYYY-MM-DD pattern — schema validation failure
- Empty rows array — minItems constraint violation
- field selector value not in enum ['duplicate_rows','total_rows'] — invalid input error
- Non-numeric values in duplicate_rows or total_rows beyond allowed null — type error

## How this service works

Duplicate observations — Record quality audit + String normalisation + Numeric distribution: Record quality audit + String normalisation + Numeric distribution for supplied duplicate observations records (duplicate_rows, total_rows). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Three independent analytical reports delivered together: (1) a record quality audit covering completeness, consistency, and structural validity of the supplied rows; (2) a string normalisation report covering the dataset_group and other string fields; and (3) a numeric distribution report with quantiles, spread, and summary statistics for the selected numeric field (duplicate_rows or total_rows). All analysis is performed locally on the supplied data with no external lookups.
