# Join Coverage Analytics: Equal-Width Histogram + Date-by-Category Pivot

> Join Coverage Analytics: Equal-Width Histogram + Date-by-Category Pivot 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).

Runs two local analytical reports on join coverage data — an equal-width histogram and a date-by-category pivot — for up to 200 rows of matched_rows/source_rows data.

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-equal-width-histogram-date-by-category-pivot-a20c7e25 -d '<json body>'
```

Example prompt: I have 150 rows of join coverage data with matched_rows and source_rows per dataset group and date — can you run an equal-width histogram with 10 bins on matched_rows and also pivot it by date and category for me?

## When to prefer this

Choose this endpoint when you need both a distribution histogram and a date-category pivot on join coverage metrics (matched_rows or source_rows) in a single low-cost call. It is ideal for data engineers who want a quick analytical snapshot of join performance across pipeline segments without building custom analytics. Prefer it over general-purpose analytics tools when working within an x402 micropayment workflow and when data fits within 200 rows.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (non YYYY-MM-DD) causes row validation failure
- bins value outside 1–30 range returns validation error
- Null values in matched_rows or source_rows may affect histogram bin calculations
- Missing required fields (row_id, dataset_group, date) cause row-level errors
- Payment of 0.01 USDC not completed results in 402 response

## How this service works

Join coverage — Equal-width histogram + Date by category pivot: Equal-width histogram + Date by category pivot 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 analytical reports: (1) an equal-width histogram of the chosen field (matched_rows or source_rows) divided into the specified number of bins with row counts per bin, and (2) a pivot table showing the selected metric aggregated by date and dataset_group category. Results are computed locally on the supplied data with no external lookups.
