# Ownership Record Completeness — Adjacent Row Changes + Secondary-Measure Weighted Mean

> Ownership Record Completeness — 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 2026-10-27).

Computes adjacent row changes and secondary-measure weighted mean analytics on ownership record completeness data (documented_links, required_links) for up to 200 rows in two 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-secondary-measure-9a1ed800 -d '<json body>'
```

Example prompt: Run both the adjacent row changes and secondary-measure weighted mean analysis on my ownership completeness records — I have 4 rows with company groups 'group-a' and 'group-b', dates from 2026-10-01 to 2026-10-04, and documented_links values of 10, 20, 15, 30 against required_links of 1, 2, 3, 4 — use documented_links as the primary field.

## When to prefer this

Choose this endpoint when you need two simultaneous local statistical analyses — adjacent row change detection and weighted mean computation — on ownership record completeness data with documented and required link counts, without needing any live external data lookups or predictions. Best suited for batch audit workflows processing up to 200 rows at $0.01 per call.

## Known failure modes

- Exceeding 200 rows returns an error or truncation
- Missing required fields (row_id, date, documented_links, required_links) causes validation failure
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Null values in numeric fields may affect weighted mean calculation
- Field enum value outside 'documented_links' or 'required_links' causes rejection

## How this service works

Ownership record completeness — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean 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

Returns two independent analytical reports: (1) adjacent row changes showing differences between consecutive rows for the selected field, and (2) a secondary-measure weighted mean computed across the supplied ownership record completeness data. Both reports are derived from the supplied rows without external lookups.
