# Ownership Record Completeness — Two-Measure Correlation + Secondary-Measure Weighted Mean

> Ownership Record Completeness — Two-Measure Correlation + 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 2026-10-16).

Computes a two-measure Pearson/Spearman correlation and a secondary-measure weighted mean for ownership record completeness data (documented_links vs required_links) 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 ownership-record-completeness-two-measure-correlation-secondary-6fafaa00 -d '<json body>'
```

Example prompt: I have ownership completeness records for my company groups — can you run the two-measure correlation and secondary weighted mean analysis on my documented_links and required_links data? I have about 50 rows covering group-a and group-b from October 2026, and I want to analyze the documented_links field.

## When to prefer this

Choose this endpoint when you need fast, local statistical analysis — specifically a two-measure correlation and weighted mean — on ownership record completeness data (documented_links vs required_links) for up to 200 rows across company groups. It is ideal when you want two bundled analytical reports at low cost ($0.01 USDC) and do not need live data lookup, external enrichment, or predictive modeling. Prefer alternatives if you need more than 200 rows, real-time data, or different analytical operations (e.g., histograms, outlier detection).

## Known failure modes

- Input array is empty or missing — minItems:1 validation error
- More than 200 rows supplied — maxItems:200 validation error
- Invalid date format (not YYYY-MM-DD) — pattern validation failure
- required_links or documented_links values exceed numeric bounds — range validation error
- field enum value not one of 'documented_links' or 'required_links' — enum validation error
- Insufficient numeric variance in input data to compute meaningful correlation — may return null or degenerate result
- Payment not fulfilled — x402 payment required error

## How this service works

Ownership record completeness — Two-measure correlation + Secondary-measure weighted mean: Two-measure correlation + 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) a two-measure correlation between documented_links and required_links across the supplied rows, and (2) a secondary-measure weighted mean for the selected field — both computed locally using shared analytical engines on the supplied data, with no external lookups or live data access.
