# Ownership Record Completeness — Duplicate Key Report + Equal-Width Histogram

> Ownership Record Completeness — Duplicate Key Report + 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 supplied ownership record completeness data (documented_links, required_links) to produce a duplicate key report and an equal-width histogram in a single call.

## 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-duplicate-key-report-equal-width-4425cd98 -d '<json body>'
```

Example prompt: Can you run a duplicate key report and a 10-bin equal-width histogram on my ownership completeness records for the documented_links field? Here are my rows: row-1, group-a, 2024-01-01, documented_links=5, required_links=10; row-2, group-b, 2024-01-02, documented_links=15, required_links=10; row-3, group-a, 2024-01-01, documented_links=5, required_links=8.

## When to prefer this

Choose this endpoint when you need to simultaneously check for duplicate keys and understand the value distribution of ownership record completeness metrics (documented_links or required_links) in a single low-cost call. It is purpose-built for ownership record data with company_group and date dimensions, and is ideal for data quality audits before reporting or ingestion pipelines. Prefer it over generic statistics tools when your data fits the ownership record schema and you need both deduplication and histogram analysis in one step for up to 200 rows at $0.01.

## Known failure modes

- Missing required row fields (row_id, date, documented_links, required_links) causes validation error
- Exceeding 200 rows returns an error or truncation
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- bins value outside 1–30 range is rejected
- Null values in numeric fields may affect histogram computation
- Empty rows array rejected (minItems: 1)

## How this service works

Ownership record completeness — Duplicate key report + Equal-width histogram: Duplicate key report + 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 analytical reports: (1) a duplicate key report identifying any rows with repeated key combinations, and (2) an equal-width histogram showing the frequency distribution of the selected field (documented_links or required_links) across up to 200 supplied rows, with a configurable number of bins (1–30, default 5).
