# Ownership Record Completeness — Category Frequencies + Daily Sum Series

> Ownership Record Completeness — Category Frequencies + Daily Sum Series 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 by computing category frequencies and a daily sum time series for documented_links and required_links fields 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-category-frequencies-daily-sum-series-9e3da1a8 -d '<json body>'
```

Example prompt: I have ownership record completeness data for two company groups over the past week — can you run a category frequency report and a daily sum series on the documented_links field for up to 200 rows I'll supply?

## When to prefer this

Choose this endpoint when you need both a categorical frequency breakdown and a daily aggregated time series from ownership record completeness data in a single low-cost call ($0.01 USDC for both reports). It is ideal for auditing link documentation rates across company groups without any external data lookup or live system access — pure local analytics on supplied row data.

## Known failure modes

- Missing required fields (row_id, company_group, date, documented_links, required_links) causes validation error
- Date values not matching YYYY-MM-DD pattern are rejected
- More than 200 rows submitted exceeds the maxItems limit
- Null numeric values may affect sum calculations in the daily series
- row_id values exceeding 80 characters are rejected

## How this service works

Ownership record completeness — Category frequencies + Daily sum series: Category frequencies + Daily sum series 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) category frequency counts showing how often each company_group value appears in the supplied records, and (2) a daily sum time series aggregating the selected numeric field (documented_links or required_links) by date — all computed locally from the supplied data with no external lookups.
