# Business Directory Coverage — Numeric Distribution + IQR Outlier Flags

> Business Directory Coverage — Numeric Distribution + 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 numeric distribution statistics and IQR-based outlier flags for business directory coverage metrics (listed_entities, verified_entities) across supplied 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-numeric-distribution-iqr-outlier-flags-9722a2d5 -d '<json body>'
```

Example prompt: Analyze the distribution of listed_entities in my business directory coverage data and flag any IQR outliers — here are my rows: row-1 group-a 2026-10-01 listed_entities=10 verified_entities=1, row-2 group-b 2026-10-02 listed_entities=20 verified_entities=2, row-3 group-a 2026-10-03 listed_entities=15 verified_entities=3, row-4 group-b 2026-10-04 listed_entities=30 verified_entities=4.

## When to prefer this

Choose this endpoint when you have batch business directory coverage data (listed_entities, verified_entities) and need quick statistical distribution summaries plus IQR-based outlier detection without any external lookups or live data fetching. Ideal for offline analytical pipelines, data quality checks on directory datasets, and anomaly flagging on up to 200 rows in a single low-cost call.

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows exceeds the limit and will be rejected
- Invalid date format (not YYYY-MM-DD) fails schema validation
- row_id missing or empty string causes validation error
- Non-numeric or out-of-range values for listed_entities/verified_entities rejected
- Invalid field enum value (not listed_entities or verified_entities) causes error
- Payment of 0.01 USDC not completed blocks execution

## How this service works

Business directory coverage — Numeric distribution + IQR outlier flags: Numeric distribution + 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 up to 2 statistical reports (one per selected field) covering numeric distribution metrics (min, max, mean, median, quartiles, IQR) and IQR-based outlier flags identifying which rows fall outside the expected range, for up to 200 supplied rows.
