# Release Readiness Secondary-Measure Weighted Mean + Keyed Dataset Comparison

> Release Readiness Secondary-Measure Weighted Mean + 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 2026-10-24).

Computes a secondary-measure weighted mean and performs a keyed dataset comparison for release readiness records (checks_passed, checks_total) across up to 200 rows in two independent reports.

## 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-readiness-secondary-measure-weighted-mean-keyed-dataset-a6f237de -d '<json body>'
```

Example prompt: I have two batches of release readiness records — each up to 200 rows with fields row_id, component, date, checks_passed, and checks_total — can you compute the secondary-measure weighted mean for checks_passed across the primary dataset and then compare it key-by-key against the second dataset?

## When to prefer this

Choose this endpoint when you need both a weighted mean aggregation (using one measure as the weight for another) and a row-keyed comparison between two release readiness datasets in a single call. It is purpose-built for release readiness data with checks_passed and checks_total fields, making it ideal for CI/CD pipelines, QA gate audits, and sprint-over-sprint release health comparisons. Prefer it over generic stats APIs when your data is already structured with row_id, component, and date identifiers.

## Known failure modes

- Missing required fields (row_id, component, date, checks_passed, checks_total) cause validation errors
- Exceeding 200 rows per dataset returns an error
- Invalid date format (non-YYYY-MM-DD) causes schema rejection
- Null values in numeric fields may affect weighted mean calculation
- Mismatched row_ids between primary and comparison datasets result in unmatched keys in comparison report

## How this service works

Release readiness — Secondary-measure weighted mean + Keyed dataset comparison: Secondary-measure weighted mean + Keyed dataset comparison for supplied release readiness records (checks_passed, checks_total). 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 secondary-measure weighted mean of the selected field (checks_passed or checks_total) across the primary dataset, and (2) a keyed dataset comparison between the primary and secondary datasets, highlighting differences by row_id. All computation is performed locally with no external lookups.
