# Ownership Record Completeness — Grouped Numeric Summary + Equal-Width Histogram

> Ownership Record Completeness — Grouped Numeric Summary + Equal-Width Histogram 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).

Analyzes ownership record completeness data (documented_links, required_links) by generating a grouped numeric summary and an equal-width histogram 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-grouped-numeric-summary-equal-width-9030515f -d '<json body>'
```

Example prompt: Can you analyze these ownership records and give me a grouped numeric summary plus a 10-bin equal-width histogram for the documented_links field? I have 4 rows across two company groups: group-a (row-1: date 2026-10-01, required_links 1, documented_links 10) and group-b (row-2: date 2026-10-02, required_links 2, documented_links 20).

## When to prefer this

Choose this endpoint when you have up to 200 ownership completeness records and need both a grouped statistical summary and a histogram of either documented_links or required_links in a single low-cost call ($0.01 USDC). It is ideal for offline/supplied-data analytics where no live lookup or external data enrichment is needed — particularly when analyzing corporate ownership link completeness grouped by company segment.

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows submitted exceeds the maximum and will be rejected
- Invalid date format (not YYYY-MM-DD) causes validation failure
- bins value outside 1–30 range is rejected
- Null values in documented_links or required_links may affect histogram binning
- Missing required fields (row_id, company_group, date) cause schema validation errors

## How this service works

Ownership record completeness — Grouped numeric summary + Equal-width histogram: Grouped numeric summary + Equal-width histogram 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 sharing the same input data: (1) a grouped numeric summary breaking down statistics (e.g. count, mean, min, max) of the selected field (documented_links or required_links) segmented by company_group, and (2) an equal-width histogram dividing the field's value range into the specified number of bins (1–30, default 5) with counts per bin.
