# Ownership Record Completeness — Equal-Width Histogram + Keyed Dataset Comparison

> Ownership Record Completeness — Equal-Width Histogram + Keyed Dataset Comparison 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).

Generates an equal-width histogram and a keyed dataset comparison report for ownership record completeness data (documented_links vs required_links) across up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-equal-width-histogram-keyed-dataset-e6eeb3c9 -d '<json body>'
```

Example prompt: Can you run a completeness analysis on our ownership records? I have 50 rows with row_id, company_group, date, documented_links, and required_links fields — use 10 bins for the histogram and compare them against our baseline dataset using the documented_links field.

## When to prefer this

Choose this endpoint when you need local, offline statistical analysis of ownership record completeness data — specifically when you want both a histogram of value distributions and a keyed comparison between two datasets in a single call. Ideal for data quality audits, compliance checks, and period-over-period benchmarking of documented vs required ownership links without any external data lookups or predictions.

## Known failure modes

- Exceeds 200 row limit — request rejected
- Missing required fields (row_id, company_group, date, documented_links, required_links) — validation error
- Invalid date format (must be YYYY-MM-DD) — schema validation failure
- bins value out of range (must be 1–30) — rejected
- Null values in numeric fields may affect histogram accuracy
- Payment not received or insufficient USDC — 402 response

## How this service works

Ownership record completeness — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison 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) an equal-width histogram showing the distribution of the selected field (documented_links or required_links) across the supplied rows, bucketed into the specified number of bins; and (2) a keyed dataset comparison that matches rows between the primary and secondary datasets by key and highlights differences in completeness metrics.
