# Business Directory Coverage — Exact Row Deduplication + Two-Measure Correlation

> Business Directory Coverage — Exact Row Deduplication + 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 2026-10-20).

Deduplicates business directory coverage records and computes two-measure correlation (listed_entities vs verified_entities) across 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 business-directory-coverage-exact-row-deduplication-two-measure-3460b176 -d '<json body>'
```

Example prompt: I have a business directory dataset with 4 rows — row-1 for group-a on 2026-10-01 with 10 listed and 1 verified, row-2 for group-b on 2026-10-02 with 20 listed and 2 verified, row-3 for group-a on 2026-10-03 with 15 listed and 3 verified, row-4 for group-b on 2026-10-04 with 30 listed and 4 verified — can you deduplicate those records and give me two correlation reports between the listed and verified entity counts?

## When to prefer this

Choose this endpoint when you have business directory coverage data with listed and verified entity counts and need both exact duplicate removal and a statistical correlation between those two measures in a single $0.01 call. Prefer this over generic deduplication tools when your data specifically has the company_group, date, listed_entities, and verified_entities schema. Best suited for small to medium datasets (up to 200 rows) where offline analytical computation is sufficient and no live data enrichment or external validation is needed.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, date, listed_entities, verified_entities) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- listed_entities or verified_entities values outside allowed numeric range — validation error
- Empty rows array — minimum 1 item required
- All rows are null for one measure — correlation computation may fail or return undefined

## How this service works

Business directory coverage — Exact row deduplication + Two-measure correlation: Exact row deduplication + 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

Returns two analytical reports: (1) an exact row deduplication report identifying and removing duplicate rows from the input dataset, and (2) a two-measure correlation report quantifying the statistical relationship between listed_entities and verified_entities across the supplied rows. All computation is performed locally with no external data lookups.
