# Ownership Record Completeness — Adjacent Row Changes + Two-Measure Correlation

> Ownership Record Completeness — 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 2026-10-17).

Analyzes ownership record completeness data (documented_links vs required_links) by computing adjacent row changes and two-measure correlation across up to 200 rows in two bundled 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 ownership-record-completeness-adjacent-row-changes-two-measure-7748d931 -d '<json body>'
```

Example prompt: Run adjacent row change analysis and two-measure correlation on my ownership completeness records — here are 4 rows with company_group, date, documented_links, and required_links values — focus on the documented_links field.

## When to prefer this

Choose this endpoint when you need both adjacent-row change analysis AND two-measure correlation on ownership completeness data (documented vs required links) in a single $0.01 call. It is ideal for batch QA, compliance reporting, or data auditing workflows where you have up to 200 pre-collected rows and want two complementary statistical views without external lookups or live data access.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Missing required fields (row_id, date, documented_links, required_links) cause validation errors
- Invalid date format (non YYYY-MM-DD) fails schema validation
- Null values in numeric fields may affect correlation computation
- Fewer than 2 rows provided makes adjacent row change analysis trivial or empty

## How this service works

Ownership record completeness — Adjacent row changes + Two-measure correlation: Adjacent row changes + Two-measure correlation for supplied ownership record completeness records (documented_links, required_links). 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

Two analytical reports: (1) adjacent row changes showing delta values between consecutive rows for the selected measure, and (2) a two-measure correlation report comparing documented_links and required_links across all supplied rows. Both are computed locally with no external lookups, covering up to 200 input rows.
