# Business Directory Coverage Analyzer — Category Frequencies & IQR Outlier Flags

> Business Directory Coverage Analyzer — Category Frequencies & IQR Outlier Flags 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 frequencies and IQR-based outlier flags for business directory coverage metrics (listed_entities, verified_entities) across up to 200 supplied rows, producing 2 independent analytical reports.

## 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-analyzer-category-frequencies-iqr-outlier-9a6fa592 -d '<json body>'
```

Example prompt: Can you run category frequency analysis and IQR outlier detection on my business directory coverage data? I have rows for group-a and group-b from October 2026 with listed_entities values like 10, 20, 15, 30 — flag any outliers in the listed_entities field and give me the frequency breakdown.

## When to prefer this

Choose this endpoint when you have tabular business directory coverage data (listed_entities, verified_entities) and need both a frequency distribution and IQR outlier detection in a single $0.01 call, without sending data to an external prediction or lookup service. Best for batch analysis of up to 200 rows where local statistical computation is sufficient and no live data enrichment is needed.

## Known failure modes

- Missing required fields (row_id, date, listed_entities, verified_entities) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- More than 200 rows submitted — exceeds maxItems limit
- All null values for the selected field produce empty or degenerate outlier reports
- row_id exceeding 80 characters is rejected
- Payment of 0.01 USDC not included — x402 payment required before response

## How this service works

Business directory coverage — Category frequencies + IQR outlier flags: Category frequencies + IQR outlier flags 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 2 independent analytical reports: (1) a category frequency breakdown showing how often each company_group appears and value distributions for the selected field (listed_entities or verified_entities), and (2) IQR-based outlier flags identifying which rows fall outside the interquartile range for the selected metric. Analysis covers up to 200 input rows with no external data lookups.
