# Duplicate Observations — Daily Sum Series + Keyed Dataset Comparison

> Duplicate Observations — Daily Sum Series + 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 2026-10-16).

Analyzes duplicate observation records by generating a daily sum time series and a keyed dataset comparison report for up to 200 rows of supplied data.

## 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-daily-sum-series-keyed-dataset-comparison-63d45d98 -d '<json body>'
```

Example prompt: I have two sets of duplicate observation records (up to 200 rows each) with date, row_id, dataset_group, duplicate_rows, and total_rows fields — can you run a daily sum series and a keyed dataset comparison on the duplicate_rows field for both datasets?

## When to prefer this

Choose this endpoint when you need both a daily aggregated time series and a row-keyed comparison between two datasets of duplicate observation records in a single call at minimal cost ($0.01 USDC for both reports). Ideal for data quality auditing pipelines where you want to track duplication trends over time and simultaneously diff two versions of the same dataset without relying on external data sources or live lookups.

## Known failure modes

- Fewer than 1 row supplied — rejected by minItems constraint
- More than 200 rows supplied — rejected by maxItems constraint
- Missing required fields (row_id, dataset_group, date, duplicate_rows, total_rows) — validation error
- Date values not matching YYYY-MM-DD format — pattern validation failure
- row_id exceeding 80 characters — field length validation error
- field enum value not one of 'duplicate_rows' or 'total_rows' — rejected
- Numeric values outside ±1,000,000,000,000 range — rejected
- Payment not fulfilled — 402 Payment Required response

## How this service works

Duplicate observations — Daily sum series + Keyed dataset comparison: Daily sum series + 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) a daily sum series aggregating the selected field (duplicate_rows or total_rows) by date across the supplied records, and (2) a keyed dataset comparison report showing differences between the primary rows dataset and the secondary other dataset, matched by row_id. Both reports are computed locally with no external lookups.
