# Ownership Record Completeness — String Normalisation + Equal-Width Histogram

> Ownership Record Completeness — String Normalisation + 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).

Runs string normalisation and equal-width histogram analysis on ownership record completeness data (documented_links, required_links) for 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-string-normalisation-equal-width-2eb9fec2 -d '<json body>'
```

Example prompt: Can you run a string normalisation and equal-width histogram on my ownership record completeness data — I have 4 rows for company groups A and B with documented_links and required_links values, using 5 bins on the documented_links field?

## When to prefer this

Choose this endpoint when you need both string normalisation and equal-width histogram analysis on ownership record completeness data (documented_links and required_links) in a single low-cost call. It is ideal for data quality checks, compliance audits, and frequency distribution analysis of ownership documentation metrics. Use it when your dataset is under 200 rows and you want two bundled local analytical reports without any external lookups or live data.

## Known failure modes

- More than 200 rows submitted — request rejected
- Missing required fields (row_id, company_group, date, documented_links, required_links) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- bins value outside 1–30 range — rejected
- field value not one of documented_links or required_links — enum validation error
- All numeric values null — histogram may be empty or degenerate

## How this service works

Ownership record completeness — String normalisation + Equal-width histogram: String normalisation + 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

Two analytical reports: a string normalisation report (cleaning/standardising the string fields in the supplied rows) and an equal-width histogram report (frequency distribution of the chosen numeric field — documented_links or required_links — divided into the specified number of equal-width bins), covering up to 200 supplied rows.
