# Business Directory Coverage Trailing Mean & Missing-Value Fill

> Business Directory Coverage Trailing Mean & 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 2026-10-20).

Computes a trailing mean time series and fills missing values in business directory coverage data (listed_entities, verified_entities) for 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-trailing-mean-missing-value-fill-b6fac673 -d '<json body>'
```

Example prompt: I have business directory coverage records for two groups across 4 dates — can you compute a trailing mean series with a window of 2 and fill any missing listed_entities values using the median, for up to 4 rows of data?

## When to prefer this

Choose this endpoint when you have tabular business directory coverage data (listed_entities, verified_entities) and need offline rolling-window smoothing plus missing-value imputation without any external lookup or live data fetch. Ideal for batch preprocessing of up to 200 rows at low cost ($0.01 USDC for both reports). Not suitable if you need real-time data retrieval, predictions, or coverage data you don't already possess.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Window size larger than number of rows per group — trailing mean may be undefined for early rows
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Missing required fields (row_id, date, company_group) — validation failure
- All values null for a group — fill method may return NaN or zero depending on method chosen

## How this service works

Business directory coverage — Trailing mean series + Explicit missing-value fill: Trailing mean series + 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 trailing mean series showing smoothed values over the specified window for the chosen field, and (2) the same dataset with missing values explicitly filled using the selected method (zero, mean, or median). Results cover up to 200 input rows grouped by company_group and date.
