# Ownership Record Completeness — Daily Sum Series + Explicit Missing-Value Fill

> Ownership Record Completeness — Daily Sum Series + Explicit Missing-Value Fill 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 daily sum time series and fills missing values (zero, mean, or median) for ownership record completeness fields (documented_links, required_links) across up to 200 rows, returning two analytical reports.

## 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-daily-sum-series-explicit-missing-value-c0db6594 -d '<json body>'
```

Example prompt: I have a set of ownership records with documented_links and required_links per company group and date — can you compute the daily sum series for documented_links and fill in any missing values using median imputation? I have about 50 rows across groups A and B from October 2026.

## When to prefer this

Choose this endpoint when you need both a daily sum time series and explicit missing-value imputation for ownership record completeness data (documented_links / required_links) in a single call. It is ideal for compliance workflows, audit pipelines, or data quality checks where you have up to 200 structured rows and want two complementary analytical views without any external data fetching or prediction.

## Known failure modes

- Missing required fields (row_id, date, company_group) causes validation failure
- More than 200 rows submitted exceeds the maxItems limit and is rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation error
- Unrecognized fill method or field value outside allowed enums returns an error
- Numeric values outside ±1,000,000,000,000 are rejected by schema bounds

## How this service works

Ownership record completeness — Daily sum series + Explicit missing-value fill: Daily sum series + Explicit missing-value fill 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 per call: (1) a daily sum time series aggregating the selected field (documented_links or required_links) by date, and (2) a version of the input data with missing values explicitly filled using the chosen method (zero, mean, or median). Both reports are computed locally from the supplied data with no external lookups.
