# Business Directory Coverage — Grouped Summary & Trailing Mean Series

> Business Directory Coverage — Grouped Summary & 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 2026-10-17).

Computes a grouped numeric summary and a trailing mean time series for business directory coverage data (listed_entities, verified_entities) across up to 200 rows.

## 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-summary-trailing-mean-series-f82932ed -d '<json body>'
```

Example prompt: Run two analytics reports on my business directory coverage data — a grouped numeric summary and a trailing mean series with a window of 7 — for listed_entities, across these 200 rows grouped by company_group with dates from 2025-01-01 to 2025-07-18.

## When to prefer this

Choose this endpoint when you have up to 200 rows of business directory coverage data (listed and verified entity counts) and need both a grouped statistical summary by company group and a rolling mean time series in a single low-cost call. Prefer it over general analytics tools when you want a quick, structured dual-report output without external data access or prediction — particularly useful for periodic audits, coverage benchmarking, or trend spotting across named business groups.

## Known failure modes

- Missing required fields (row_id, date, company_group, listed_entities, verified_entities) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- Fewer than 1 or more than 200 rows cause schema validation failure
- Window value outside 2–200 range is rejected
- Null numeric values in the selected field may affect trailing mean computation
- Invalid field enum value (not 'listed_entities' or 'verified_entities') causes error

## How this service works

Business directory coverage — Grouped numeric summary + Trailing mean series: Grouped numeric summary + 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 reports: (1) a grouped numeric summary showing aggregate statistics (e.g. count, mean, min, max) for the specified field broken down by company_group, and (2) a trailing mean time series showing rolling averages over the specified window for the field across the supplied rows. Both reports are computed locally from the supplied data with no external lookups.
