# Business Directory Coverage — Adjacent Row Changes + Secondary-Measure Weighted Mean

> Business Directory Coverage — Adjacent Row Changes + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Computes adjacent row changes and secondary-measure weighted mean analytics on business directory coverage data (listed_entities, verified_entities) for up to 200 rows in two 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 business-directory-coverage-adjacent-row-changes-secondary-measure-254b6a94 -d '<json body>'
```

Example prompt: I have business directory coverage data with listed and verified entity counts across groups and dates — can you run adjacent row changes plus a secondary-measure weighted mean on up to 200 rows for the listed_entities field?

## When to prefer this

Choose this endpoint when you have tabular business directory coverage data with listed and verified entity counts and need both a row-by-row delta analysis and a weighted mean statistic in a single low-cost call. It is well-suited for batch analytical workflows on up to 200 rows where no external data enrichment, live lookup, or prediction is needed — purely deterministic statistical computation on supplied data.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) causes validation error
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Numeric values outside allowed range (-1e12 to 1e12) cause validation failure
- Empty rows array returns error
- Invalid field enum value (not listed_entities or verified_entities) causes rejection

## How this service works

Business directory coverage — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean for supplied business directory coverage records (listed_entities, verified_entities). 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 computed locally against the supplied data: (1) adjacent row changes showing the difference between consecutive rows for the selected field, and (2) a secondary-measure weighted mean using verified_entities or listed_entities as the weighting dimension — all derived from the submitted dataset without any external lookup.
