# Business Directory Coverage — Equal-Width Histogram + Keyed Dataset Comparison

> Business Directory Coverage — Equal-Width Histogram + Keyed Dataset Comparison 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).

Runs two local analytical reports on business directory coverage data: an equal-width histogram of a chosen field and a keyed dataset comparison between two supplied row sets, for up to 200 rows.

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-equal-width-histogram-keyed-dataset-1dc16cb0 -d '<json body>'
```

Example prompt: Analyze my business directory coverage records — I have two datasets of up to 50 rows each with listed_entities and verified_entities per company group and date. Run an equal-width histogram (10 bins) on listed_entities and compare the two datasets by row key.

## When to prefer this

Choose this endpoint when you have business directory coverage data (listed and verified entity counts) and need both a distribution histogram and a two-dataset comparison in a single call. It is ideal for offline/local analysis of supplied data where no live lookup or external enrichment is needed. Prefer this over general analytics tools when working specifically with directory coverage fields and needing both report types bundled for $0.01 USDC.

## Known failure modes

- Exceeding 200 rows in either dataset returns an error or truncation
- Invalid date format (not YYYY-MM-DD) causes validation failure
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) causes rejection
- bin count outside 1–30 range is rejected
- Null values in numeric fields may affect histogram accuracy
- Payment failure (x402) blocks execution

## How this service works

Business directory coverage — Equal-width histogram + Keyed dataset comparison: Equal-width histogram + Keyed dataset comparison 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 independent analytical reports: (1) an equal-width histogram showing bin ranges and frequency counts for the selected field (listed_entities or verified_entities) across the primary row set, and (2) a keyed dataset comparison between the primary rows and the secondary (other) rows, highlighting differences by row_id. No external lookups or predictions are performed — all computation is local.
