# Business Directory Coverage — Numeric Row Ordering + Two-Measure Correlation

> Business Directory Coverage — Numeric Row Ordering + Two-Measure Correlation 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 numeric row ordering and two-measure correlation analysis on business directory coverage data (listed_entities, verified_entities) for up to 200 rows, returning two independent analytical reports.

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 business-directory-coverage-numeric-row-ordering-two-measure-4ad0d493 -d '<json body>'
```

Example prompt: I have business directory coverage data for two company groups over four dates — can you rank the rows numerically by listed_entities and also compute the correlation between listed_entities and verified_entities across all rows?

## When to prefer this

Choose this endpoint when you need both numeric ordering and two-measure correlation analysis on business directory coverage data (listed_entities + verified_entities) in a single low-cost call. It is purpose-built for this specific pair of measures and schema, making it more efficient than a general-purpose statistical API when your data fits the directory coverage schema with up to 200 rows.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, date, listed_entities, verified_entities) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Null values in both measure columns may degrade or invalidate correlation computation
- Field enum value not in ['listed_entities','verified_entities'] causes rejection

## How this service works

Business directory coverage — Numeric row ordering + Two-measure correlation: Numeric row ordering + Two-measure correlation 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 independent analytical reports: (1) a numeric row ordering report ranking the supplied rows by the chosen field (listed_entities or verified_entities), and (2) a two-measure correlation report quantifying the statistical relationship between listed_entities and verified_entities across the supplied rows. No external lookups or predictions are made — all analysis is performed locally on the supplied data.
