# Release Note Coverage Deduplication and Secondary-Measure Weighted Mean

> Release Note Coverage Deduplication and Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-03).

Deduplicates release note coverage rows exactly and computes a secondary-measure weighted mean across documented_changes and released_changes fields, producing two analytical reports from 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 release-note-coverage-deduplication-and-secondary-measure-weighted-mean-75fd9764 -d '<json body>'
```

Example prompt: Can you deduplicate my release note coverage records and compute a secondary-measure weighted mean on the documented_changes field? I have data for four releases across two groups (group-a and group-b) with dates ranging from 2026-10-01 to 2026-10-04 — I need both the dedup report and the weighted mean report.

## When to prefer this

Choose this endpoint when you need both exact row deduplication and a secondary-measure weighted mean on release note coverage data (documented_changes / released_changes) in a single low-cost call. It is purpose-built for release/changelog coverage analytics with up to 200 rows and returns two reports simultaneously, making it efficient for batch cleanup and aggregation tasks without requiring external lookups or live data.

## Known failure modes

- More than 200 rows submitted — request rejected with row limit error
- Missing required fields (row_id, date, document_group) — validation error returned
- Invalid date format not matching YYYY-MM-DD pattern — schema validation failure
- Null values in both documented_changes and released_changes — weighted mean computation may be undefined
- Empty rows array — minimum 1 item required, returns error

## How this service works

Release note coverage — Exact row deduplication + Secondary-measure weighted mean: Exact row deduplication + Secondary-measure weighted mean for supplied release note coverage records (documented_changes, released_changes). 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) an exact row-deduplicated version of the supplied release note coverage rows, and (2) a secondary-measure weighted mean computed over the chosen field (documented_changes or released_changes), grouped or aggregated across the provided rows. Up to 200 input rows supported per call.
