# Business Directory Coverage — Category Frequencies + Trailing Mean Series

> Business Directory Coverage — Category Frequencies + Trailing Mean Series 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 category frequency distributions and trailing mean time series for business directory coverage metrics (listed_entities, verified_entities) across up to 200 rows of supplied data.

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-category-frequencies-trailing-mean-series-4fcb1250 -d '<json body>'
```

Example prompt: Run category frequency counts and a trailing mean series (window of 7) on my business directory coverage data — I have rows with company groups like 'region-west' and 'region-east', dates from 2025-01-01 to 2025-01-14, and I want to analyze the listed_entities field.

## When to prefer this

Choose this endpoint when you have tabular business directory coverage data (listed vs verified entity counts per company group over time) and need both a category frequency summary and a trailing mean time series in a single low-cost call. It is ideal for offline or batch analytics on your own dataset without requiring external data sources or live lookups. At $0.01 for up to 200 rows with two reports, it is cost-efficient for routine directory coverage analysis.

## Known failure modes

- Missing required fields (row_id, date, listed_entities, verified_entities) causes validation error
- More than 200 rows submitted — exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Window value outside range 2–200 causes validation failure
- All null values in the selected field may produce empty or degenerate series
- Payment not included or insufficient USDC causes x402 payment required response

## How this service works

Business directory coverage — Category frequencies + Trailing mean series: Category frequencies + Trailing mean series 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 for the supplied data: (1) a category frequency report showing how often each company_group (or other category) appears in the dataset, and (2) a trailing mean series for the chosen field (listed_entities or verified_entities) computed over the specified rolling window. Both reports are computed locally from the submitted rows with no external data lookups.
