# Business Directory Coverage — Two-Measure Correlation + Keyed Dataset Comparison

> Business Directory Coverage — Two-Measure Correlation + 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 2026-10-16).

Runs two local analytical reports (Pearson/Spearman correlation between listed_entities and verified_entities, plus a keyed row-by-row dataset comparison) on supplied business directory coverage records, up to 200 rows per call.

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-two-measure-correlation-keyed-dataset-05df3b84 -d '<json body>'
```

Example prompt: I have two sets of business directory coverage records (up to 200 rows each, with listed_entities and verified_entities per company group and date) — can you run a correlation analysis between those two measures and also compare the two datasets row-by-row using the row_id as the key?

## When to prefer this

Choose this endpoint when you have business directory coverage data with listed and verified entity counts and need both a statistical correlation between those two measures AND a structured row-level comparison between two dataset versions in a single $0.01 call. Ideal for QA pipelines, coverage audits, or periodic diff reporting on directory snapshots without any external data lookup.

## Known failure modes

- Missing required fields (row_id, date, listed_entities, verified_entities) causes validation error
- Exceeding 200 rows triggers a rejection or truncation
- Malformed date strings not matching YYYY-MM-DD pattern fail schema validation
- Null values in both measures may reduce correlation reliability
- Mismatched row_id keys between primary and comparison datasets result in unmatched rows in comparison report
- Payment failure (insufficient USDC) blocks execution

## How this service works

Business directory coverage — Two-measure correlation + Keyed dataset comparison: Two-measure correlation + 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) a two-measure correlation report quantifying the statistical relationship between listed_entities and verified_entities across all supplied rows, and (2) a keyed dataset comparison report identifying matches, mismatches, and differences between the primary and comparison datasets aligned by row_id.
