# Ownership Record Completeness Analyzer — Base-100 Index + Missing Value Fill

> Ownership Record Completeness Analyzer — Base-100 Index + 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 2026-10-17).

Computes a base-100 index series and fills missing values for ownership record completeness data (documented_links vs required_links), producing two analytical reports 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-analyzer-base-100-index-missing-value-c893d623 -d '<json body>'
```

Example prompt: I have ownership completeness records for two company groups over several dates — can you normalize them to a base-100 index starting from row 0 and fill any missing documented_links values using the median? I've got up to 10 rows with fields: row_id, company_group, date, documented_links, and required_links.

## When to prefer this

Choose this endpoint when you need both a base-100 normalization of ownership completeness time series AND missing value imputation in a single $0.01 call, without requiring any live data lookup, prediction, or external service. It is ideal for offline batch preparation of ownership link records (up to 200 rows) before compliance reporting, audit, or further analytics. Prefer alternatives if you need real-time enrichment, predictive scoring, or more than 200 rows per call.

## Known failure modes

- More than 200 rows submitted — API rejects with validation error
- base_index references a row index that doesn't exist in the submitted array
- All values for the selected field are null — mean/median imputation cannot be computed
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Missing required fields (row_id, documented_links, required_links) cause rejection
- Payment of 0.01 USDC not included or fails — request not processed

## How this service works

Ownership record completeness — Base-100 series + Explicit missing-value fill: Base-100 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: (1) a base-100 normalized index series where the specified base row equals 100 and all other rows are scaled proportionally, and (2) an explicit missing-value fill report where null documented_links or required_links values are replaced using the chosen method (zero, mean, or median). Both reports cover up to 200 input rows and are computed locally without external lookups.
