# Dataset Partition Sizes — Duplicate Key Report + Two-Measure Correlation

> Dataset Partition Sizes — Duplicate Key Report + Two-Measure Correlation 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).

Analyzes up to 200 dataset partition size records to produce a duplicate key report and a two-measure correlation analysis between row_count and file_mb.

## 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 dataset-partition-sizes-duplicate-key-report-two-measure-correlation-cd61a088 -d '<json body>'
```

Example prompt: Can you check my dataset partition records for duplicate row IDs and also tell me how correlated the row_count and file_mb values are? I have about 50 rows across two groups — group-a and group-b — with dates from 2026-10-01 to 2026-11-20.

## When to prefer this

Choose this endpoint when you need both duplicate key detection and a two-measure correlation analysis on dataset partition size records (row_count, file_mb) in a single low-cost call. It is ideal for data engineers auditing partition metadata quality before pipeline loads, and for analysts wanting a quick correlation check between file size and row count without writing custom code. It handles up to 200 rows per call and requires no external dependencies.

## Known failure modes

- Input rows array is empty or missing — validation error returned
- More than 200 rows submitted — request rejected due to row limit
- row_id or dataset_group fields missing or empty — schema validation failure
- date field does not match YYYY-MM-DD format — pattern validation error
- row_count or file_mb values exceed allowed numeric range — validation error
- Insufficient numeric data to compute correlation (e.g. all null values) — correlation report may return null or undefined result

## How this service works

Dataset partition sizes — Duplicate key report + Two-measure correlation: Duplicate key report + Two-measure correlation for supplied dataset partition sizes records (row_count, file_mb). 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 duplicate key report identifying any repeated row_id values within the submitted partition records, and (2) a two-measure correlation analysis quantifying the statistical relationship between the row_count and file_mb fields across the supplied rows. No external lookups or predictions are made; all analysis is performed locally on the supplied data.
