# Business Directory Coverage — Category Frequencies + Numeric Interval Filter

> Business Directory Coverage — Category Frequencies + Numeric Interval Filter 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).

Analyzes business directory coverage records to produce category frequency distributions and a numeric interval filter report for listed_entities and verified_entities fields.

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-numeric-interval-a2eab106 -d '<json body>'
```

Example prompt: I have business directory coverage records for group-a and group-b from October 2026 — can you run a category frequency report on them and also filter rows where listed_entities is between 10 and 30?

## When to prefer this

Choose this endpoint when you have up to 200 business directory coverage records and need both a categorical frequency breakdown (by company_group) and a numeric range filter on listed_entities or verified_entities in a single low-cost call. It is a pure local computation with no external data access, making it fast, deterministic, and suitable for batch reporting workflows. Prefer it over general-purpose analytics tools when cost efficiency ($0.01 for two reports) and schema-enforced inputs for business directory fields are priorities.

## Known failure modes

- More than 200 rows submitted — exceeds maxItems limit, request rejected
- Missing required fields (row_id, company_group, date, listed_entities, or verified_entities) — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- Numeric values outside allowed range (±1,000,000,000,000) — rejected by schema
- minimum greater than maximum — may return empty interval filter result
- Empty rows array — rejected by minItems:1 constraint

## How this service works

Business directory coverage — Category frequencies + Numeric interval filter: Category frequencies + Numeric interval filter 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) category frequency counts per company_group showing how often each category appears in the supplied rows, and (2) a numeric interval filter report listing rows where the chosen field (listed_entities or verified_entities) falls within the specified minimum–maximum range. Up to 200 rows processed per call, all computed locally with no external lookups.
