# Business Directory Coverage — Grouped Numeric Summary + Explicit Missing-Value Fill

> Business Directory Coverage — Grouped Numeric Summary + Explicit 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).

Computes grouped numeric summaries and fills missing values for business directory coverage records (listed_entities, verified_entities) across up to 200 supplied 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-grouped-numeric-summary-explicit-missing-c903f9d2 -d '<json body>'
```

Example prompt: I have up to 200 rows of business directory coverage data with listed_entities and verified_entities fields — some values are null — can you give me a grouped numeric summary by company_group and fill the missing verified_entities values using median imputation?

## When to prefer this

Choose this endpoint when you have pre-collected business directory coverage data (listed and verified entity counts) and need both grouped descriptive statistics by company group AND missing-value imputation in a single low-cost call ($0.01 USDC). Ideal for offline/batch analytical workflows on up to 200 rows where no live data lookup or external enrichment is needed.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems constraint
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) cause validation errors
- Invalid date format (not YYYY-MM-DD) results in schema rejection
- Invalid method value outside [zero, mean, median] causes error
- Invalid field value outside [listed_entities, verified_entities] causes error
- Empty rows array rejected due to minItems:1 constraint

## How this service works

Business directory coverage — Grouped numeric summary + Explicit missing-value fill: Grouped numeric summary + 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

Returns two analytical reports: (1) a grouped numeric summary (e.g. count, mean, min, max) of the specified field (listed_entities or verified_entities) broken down by company_group, and (2) the same dataset with missing values in the specified field explicitly filled using the chosen method (zero, mean, or median). All computed locally from the supplied rows with no external data fetched.
