# Business Directory Coverage — Category Frequencies & Adjacent Row Changes

> Business Directory Coverage — Category Frequencies & Adjacent Row Changes 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).

Analyzes up to 200 business directory coverage records to produce two reports: category frequency distribution and adjacent row changes for listed_entities or verified_entities fields.

## 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-adjacent-row-changes-f8a74646 -d '<json body>'
```

Example prompt: Can you run category frequency and adjacent row change reports on my business directory coverage data? Here are my rows: group-a on 2026-10-01 had 10 listed and 1 verified, group-b on 2026-10-02 had 20 listed and 2 verified, group-a on 2026-10-03 had 15 listed and 3 verified — analyze the listed_entities field.

## When to prefer this

Choose this endpoint when you have up to 200 business directory coverage records and need both a category frequency distribution and adjacent row change analysis in a single $0.01 call — ideal for batch offline analytics on supplied data without needing any live lookup, prediction, or external data enrichment.

## Known failure modes

- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) causes validation error
- Date strings not matching YYYY-MM-DD pattern are rejected
- Submitting more than 200 rows exceeds the maxItems limit
- Null values in listed_entities or verified_entities may affect change computation
- Invalid field enum value (not 'listed_entities' or 'verified_entities') causes rejection

## How this service works

Business directory coverage — Category frequencies + Adjacent row changes: Category frequencies + Adjacent row changes 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) category frequency counts showing how often each company_group appears in the submitted rows, and (2) adjacent row change values showing the difference in the selected field (listed_entities or verified_entities) between each consecutive row. Both reports are computed locally from supplied data with no external lookups.
