# Ownership Record Completeness — Adjacent Row Changes + Equal-Width Histogram

> Ownership Record Completeness — Adjacent Row Changes + 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 2026-10-17).

Analyzes ownership record completeness data by computing adjacent row changes and an equal-width histogram for up to 200 rows of documented/required link counts.

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-adjacent-row-changes-equal-width-cc326ddd -d '<json body>'
```

Example prompt: Run adjacent row changes and an equal-width histogram (5 bins) on my ownership completeness records for the documented_links field — I have 4 rows: row-1 group-a 2026-10-01 documented=10 required=1, row-2 group-b 2026-10-02 documented=20 required=2, row-3 group-a 2026-10-03 documented=15 required=3, row-4 group-b 2026-10-04 documented=30 required=4.

## When to prefer this

Choose this endpoint when you need two complementary statistical views — sequential change detection and distributional bucketing — on ownership record completeness data (documented vs required links) in a single $0.01 call. It is ideal for data quality audits, compliance checks, or exploratory analysis of corporate ownership link coverage across time and company groups, without needing external data sources or prediction models.

## Known failure modes

- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (row_id, company_group, date, documented_links, required_links) on any row
- Invalid date format (must be YYYY-MM-DD)
- bins value outside 1–30 range
- field value not one of documented_links or required_links
- Payment not completed via x402 protocol — request rejected
- All values null for the selected field — histogram/change computation not meaningful

## How this service works

Ownership record completeness — Adjacent row changes + Equal-width histogram: Adjacent row changes + 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) an adjacent row changes report showing the difference in the selected field (documented_links or required_links) between each consecutive row, and (2) an equal-width histogram report bucketing the field values into the specified number of bins with counts per bin. Both reports are derived locally from the supplied data with no external lookups.
