# Release Note Coverage — Record Quality Audit + Two-Measure Correlation

> Release Note Coverage — Record Quality Audit + 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 2026-10-30).

Audits record quality and computes two-measure correlation for release note coverage data (documented_changes vs released_changes) across up to 200 rows.

## 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-record-quality-audit-two-measure-correlation-fec8a7cf -d '<json body>'
```

Example prompt: Can you audit the quality of my release note coverage records and check the correlation between documented_changes and released_changes? I have 4 rows: row-1 on 2026-10-01 in group-a with 10 documented and 1 released, row-2 on 2026-10-02 in group-b with 20 documented and 2 released, row-3 on 2026-10-03 in group-a with 15 documented and 3 released, and row-4 on 2026-10-04 in group-b with 30 documented and 4 released.

## When to prefer this

Choose this endpoint when you need both a record-level data quality audit AND a statistical correlation between two numeric coverage metrics on the same dataset in a single API call. It is specifically designed for release note coverage data with documented_changes and released_changes fields, making it ideal for software teams validating documentation completeness against actual release activity. Prefer this over generic stats endpoints when you need the two bundled reports at low cost with no external data dependency.

## Known failure modes

- Empty rows array returns validation error
- More than 200 rows exceeds maxItems limit and is rejected
- Missing required fields (row_id, document_group, date, documented_changes, released_changes) cause row-level validation failure
- Malformed date strings not matching YYYY-MM-DD pattern are rejected
- Numeric values outside the allowed range (-1e12 to 1e12) are rejected
- Payment of 0.01 USDC must be included via x402 protocol or request is rejected

## How this service works

Release note coverage — Record quality audit + Two-measure correlation: Record quality audit + Two-measure correlation 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) a record quality audit identifying completeness issues, anomalies, and data quality flags across the supplied release note coverage rows; and (2) a two-measure correlation report quantifying the statistical relationship between documented_changes and released_changes fields. Both reports are generated locally from the supplied data with no external lookups.
