# Release Readiness Adjacent Row Changes & Two-Measure Correlation

> Release Readiness Adjacent Row Changes & Two-Measure Correlation 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).

Runs two local analytical reports on up to 200 release readiness rows: adjacent row change detection and correlation analysis between checks_passed and checks_total.

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-readiness-adjacent-row-changes-two-measure-correlation-7d91f261 -d '<json body>'
```

Example prompt: Analyze my release readiness data for adjacent row changes and correlation between checks_passed and checks_total — I have 4 components logged daily from 2026-10-01 to 2026-10-04 with row IDs row-1 through row-4, focusing on checks_passed.

## When to prefer this

Choose this endpoint when you need lightweight, on-demand statistical analysis of release readiness check data without sending data to an external prediction or ML service. It is ideal for DevOps pipelines that need two simultaneous local analytical reports — adjacent row deltas and inter-measure correlation — on up to 200 rows at very low cost. Prefer alternatives if you need forecasting, professional assessment, or analysis of more than 200 rows at once.

## Known failure modes

- More than 200 rows submitted — request rejected, maxItems limit exceeded
- Missing required fields (row_id, component, date, checks_passed, checks_total) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Fewer than 2 rows provided — insufficient data for adjacent row analysis or correlation
- Non-numeric values in checks_passed or checks_total — computation fails
- Payment not included or insufficient — x402 payment required error

## How this service works

Release readiness — Adjacent row changes + Two-measure correlation: Adjacent row changes + Two-measure correlation 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) an adjacent row changes report showing differences between consecutive rows for the selected field, and (2) a two-measure correlation report between checks_passed and checks_total across the supplied dataset. All analysis is performed locally on the provided data with no external lookups.
