# Business Directory Coverage — Exact Row Deduplication + Secondary-Measure Weighted Mean

> Business Directory Coverage — Exact Row Deduplication + 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 2026-10-16).

Deduplicates up to 200 rows of business directory coverage data and computes a secondary-measure weighted mean across listed_entities and verified_entities fields, returning two 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-exact-row-deduplication-secondary-measure-5f8c5cdb -d '<json body>'
```

Example prompt: Can you deduplicate these business directory coverage rows and compute a weighted mean using listed_entities as the field? I have 4 rows across two company groups (group-a and group-b) dated 2026-10-01 through 2026-10-04, with listed_entities values of 10, 20, 15, 30 and verified_entities values of 1, 2, 3, 4.

## When to prefer this

Choose this endpoint when you have tabular business directory coverage data (listed_entities, verified_entities) that needs both exact deduplication and a weighted mean computed in a single call returning two reports, all without any external data lookup or live enrichment. It is ideal for offline batch analytics on up to 200 rows at low cost ($0.01 USDC for both reports).

## Known failure modes

- Exceeds 200 row limit — request rejected
- Missing required fields (row_id, date, company_group, listed_entities, verified_entities) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null values in both measures may produce undefined weighted mean
- Invalid field enum value — rejected with schema error
- Empty rows array — rejected with minItems violation

## How this service works

Business directory coverage — Exact row deduplication + Secondary-measure weighted mean: Exact row deduplication + 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

Returns two analytical reports: (1) an exact row deduplication result showing which rows were unique versus duplicate, and (2) a secondary-measure weighted mean computed over the specified field (listed_entities or verified_entities) across all supplied rows, using the other measure as the weight. Both reports are computed locally without external lookups.
