# Join Coverage Analytics: Date-Category Pivot + Keyed Dataset Comparison

> Join Coverage Analytics: Date-Category Pivot + 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 2026-10-19).

Analyzes join coverage data (matched_rows, source_rows) by producing a date-by-category pivot table and a keyed dataset comparison report for two supplied 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 join-coverage-analytics-date-category-pivot-keyed-dataset-comparison-42b0ab9b -d '<json body>'
```

Example prompt: Can you analyze my join coverage data — I have two sets of records (up to 200 rows each) with matched_rows and source_rows fields by date and dataset_group — pivot them by date and category, and then compare the two datasets keyed by row_id using the matched_rows field?

## When to prefer this

Choose this endpoint when you have two sets of join coverage records (with matched_rows and source_rows) and need both a date-by-category pivot view and a direct keyed comparison between the two datasets in a single low-cost call. Ideal for data engineers auditing ETL join quality, comparing dataset snapshots, or reviewing how join coverage varies across groups and dates — all without needing external data or live lookups.

## Known failure modes

- More than 200 rows submitted — request rejected
- Missing required fields (row_id, dataset_group, date, matched_rows, source_rows) — validation error
- Date values not in YYYY-MM-DD format — pattern validation failure
- Numeric values outside allowed range (±1,000,000,000,000) — schema rejection
- Empty rows array — minItems violation
- Invalid field enum value (must be matched_rows or source_rows) — schema error

## How this service works

Join coverage — Date by category pivot + Keyed dataset comparison: Date by category pivot + Keyed dataset comparison for supplied join coverage records (matched_rows, source_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 date-by-category pivot table showing matched_rows or source_rows values broken out by date and dataset_group, and (2) a keyed dataset comparison report contrasting the two supplied datasets row by row using the selected field. Both reports are computed locally from the supplied data with no external lookups.
