# Time Series Completeness — Category Frequencies + Keyed Dataset Comparison

> Time Series Completeness — Category Frequencies + 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 2026-10-15).

Runs two local analytical reports on time series completeness data: category frequency distribution by group and keyed row-by-row comparison between two datasets (up to 200 rows each).

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 time-series-completeness-category-frequencies-keyed-dataset-comparison-6075ef70 -d '<json body>'
```

Example prompt: Can you run a category frequency analysis and keyed dataset comparison on my two time series completeness datasets? The first set has rows with row_id, dataset_group, date, observed_points, and expected_points — for example group-a on 2026-10-01 with 10 observed vs 1 expected — and the second dataset has similar rows with slightly different observed_points values for the same row IDs.

## When to prefer this

Choose this endpoint when you need simultaneous category frequency analysis AND a keyed row-level comparison for time series completeness data in a single $0.01 call. It is purpose-built for observed vs expected point count data with dataset_group and date dimensions, and processes up to 200 rows per dataset without any external data fetching or prediction — ideal for data quality audits, pipeline validation, and completeness monitoring workflows.

## Known failure modes

- Missing required fields (row_id, dataset_group, date, observed_points, expected_points) cause validation errors
- Date values not matching YYYY-MM-DD pattern are rejected
- Submitting more than 200 rows returns an error
- Row IDs present in one dataset but not the other may produce unmatched rows in the keyed comparison
- Null numeric values are accepted but may affect completeness calculations

## How this service works

Time series completeness — Category frequencies + Keyed dataset comparison: Category frequencies + Keyed dataset comparison for supplied time series completeness records (observed_points, expected_points). 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 category frequency table showing how often each dataset_group appears across the supplied rows, and (2) a keyed row-by-row comparison between the primary and secondary datasets, highlighting differences in observed_points and expected_points for matching row IDs. Both reports are computed locally with no external lookups.
