# Release Note Coverage — Adjacent Row Changes & Secondary-Measure Weighted Mean

> Release Note Coverage — Adjacent Row Changes & 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 2026-10-30).

Computes adjacent row changes and secondary-measure weighted mean analytics on release note coverage data (documented_changes, released_changes) for up to 200 rows, returning 2 independent statistical reports.

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 release-note-coverage-adjacent-row-changes-secondary-measure-weighted-7482e367 -d '<json body>'
```

Example prompt: Run adjacent row changes and secondary-measure weighted mean reports on my release note coverage data — I have 4 rows with dates from 2026-10-01 to 2026-10-04, document groups 'group-a' and 'group-b', documented_changes values of 10, 20, 15, 30, and released_changes of 1, 2, 3, 4 — analyze the documented_changes field.

## When to prefer this

Choose this endpoint when you need two specific statistical computations — adjacent row changes and secondary-measure weighted mean — applied to release note coverage metrics (documented_changes and released_changes). It is ideal for batch offline analysis of up to 200 rows of release documentation records without requiring live data lookups or external integrations. Prefer it over general analytics platforms when you want a lightweight, paid-per-call computation on structured release audit data at low cost ($0.01 per call for 2 reports).

## Known failure modes

- Input array empty or missing — minItems:1 not met
- More than 200 rows supplied — maxItems:200 exceeded
- Invalid date format — must match YYYY-MM-DD pattern
- row_id missing or empty — required field with minLength:1
- field enum value not one of 'documented_changes' or 'released_changes'
- Numeric values outside allowed range (-1e12 to 1e12)
- Payment of 0.01 USDC not provided — x402 payment required

## How this service works

Release note coverage — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + 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 2 independent analytical reports: (1) adjacent row changes showing the difference between consecutive rows for the selected field, and (2) a secondary-measure weighted mean across the dataset. Both reports are computed locally on the supplied data without any external lookups or predictions.
