# Ownership Record Completeness — Category Frequencies + Equal-Width Histogram

> Ownership Record Completeness — Category Frequencies + 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 category frequency counts 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-category-frequencies-equal-width-140733cf -d '<json body>'
```

Example prompt: Can you run category frequencies and a histogram with 10 bins on my ownership records — specifically the documented_links field — for these rows: row-1, group-a, 2024-01-01, documented_links=50, required_links=100; row-2, group-b, 2024-01-02, documented_links=75, required_links=100?

## When to prefer this

Use this endpoint when you need quick, local statistical summaries (frequency counts and histogram distribution) of ownership record completeness fields without any external data enrichment, prediction, or live lookups. It is ideal for data quality audits, compliance checks, or exploratory analysis of how well ownership links are documented across company groups. Prefer this over general analytics platforms when you want a lightweight, pay-per-use computation on a small batch of up to 200 rows.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (must be YYYY-MM-DD) causes row validation failure
- Missing required fields (row_id, company_group, date, documented_links, required_links) causes schema rejection
- Bins parameter out of range (must be 1–30) causes error
- Non-numeric values in documented_links or required_links fields cause computation failure
- Payment of 0.01 USDC not included or rejected causes 402 response

## How this service works

Ownership record completeness — Category frequencies + Equal-width histogram: Category frequencies + 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 independent analytical reports for up to 200 supplied rows: (1) category frequencies showing how often each distinct value or group appears in the selected field, and (2) an equal-width histogram breaking the numeric field values into the specified number of bins with counts per bin. Both reports are computed locally from the supplied data with no external lookups.
