# Ownership Record Completeness — Trailing Mean Series + Two-Measure Correlation

> Ownership Record Completeness — Trailing Mean Series + 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).

Computes trailing mean time series and two-measure correlation analysis on ownership record completeness data (documented_links vs required_links) for 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-trailing-mean-series-two-measure-623ade87 -d '<json body>'
```

Example prompt: Analyze my ownership record completeness data — I have 50 rows with documented_links and required_links values by company group and date. Can you compute a trailing mean series with a window of 5 for the documented_links field and also run a two-measure correlation between documented_links and required_links?

## When to prefer this

Choose this endpoint when you need lightweight, self-contained statistical analysis — specifically a rolling/trailing mean series and a two-measure Pearson-style correlation — on ownership record completeness data (documented vs required links) without sending data to a heavy analytics platform. Ideal for small-to-medium datasets (up to 200 rows) where cost efficiency ($0.01 for two reports) and data locality matter.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — request rejected
- window parameter larger than the number of rows — insufficient data for rolling computation
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Missing required fields (row_id, date, documented_links, required_links) — request rejected
- Null values in numeric fields may reduce effective row count for correlation

## How this service works

Ownership record completeness — Trailing mean series + Two-measure correlation: Trailing mean series + 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

Returns two analytical reports: (1) a trailing mean time series for the selected field (documented_links or required_links) computed over the specified rolling window, and (2) a two-measure correlation analysis between documented_links and required_links — both derived locally from the supplied row data without any external lookups.
