# Business Directory Coverage: Keyed Dataset Comparison + Missing-Value Fill

> Business Directory Coverage: Keyed Dataset Comparison + Missing-Value Fill 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).

Compares two business directory datasets by key and fills missing values for listed_entities and verified_entities fields across up to 200 rows, producing 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-keyed-dataset-comparison-missing-value-fill-db076b85 -d '<json body>'
```

Example prompt: Compare these two sets of business directory coverage records — one with listed_entities and verified_entities for group-a and group-b across October 2026 — and fill in any missing values, then give me both the keyed dataset comparison and the missing-value fill reports for the listed_entities field.

## When to prefer this

Choose this endpoint when you have two sets of business directory coverage records (listed_entities, verified_entities) that need to be compared by key and have null/missing values explicitly filled, and you want two separate analytical reports from a single low-cost call. Best for data quality audits, coverage gap analysis, and reconciliation tasks involving up to 200 directory rows without needing live lookups or external enrichment.

## Known failure modes

- More than 200 rows submitted — request rejected with validation error
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) — row rejected
- Date field does not match YYYY-MM-DD pattern — validation error
- Numeric values outside allowed range (-1T to +1T) — field rejected
- Empty rows array — minimum 1 item required
- Mismatched row_ids between primary and other dataset — comparison may produce incomplete results

## How this service works

Business directory coverage — Keyed dataset comparison + Explicit missing-value fill: Keyed dataset comparison + Explicit missing-value fill 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: (1) a keyed dataset comparison highlighting differences between the two supplied datasets matched by row_id, and (2) an explicit missing-value fill report for the selected field (listed_entities or verified_entities), covering up to 200 rows. No external lookups or predictions are performed — all analysis uses local engines on the supplied data.
