# Business Directory Coverage — String Normalisation + Two-Measure Correlation

> Business Directory Coverage — String Normalisation + Two-Measure Correlation 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).

Normalises strings and computes two-measure correlation analysis on business directory coverage records (listed_entities, verified_entities) 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-string-normalisation-two-measure-21d65079 -d '<json body>'
```

Example prompt: I have business directory coverage data for two groups — group-a and group-b — with dates from 2026-10-01 to 2026-10-04 and listed_entities values of 10, 20, 15, 30 and verified_entities values of 1, 2, 3, 4. Can you run the string normalisation and two-measure correlation analysis on these rows and give me both reports?

## When to prefer this

Choose this endpoint when you have up to 200 rows of business directory coverage data with listed_entities and verified_entities numeric metrics and need both string normalisation of company group labels and a statistical correlation between those two measures in a single low-cost call ($0.01 USDC). It is a purely local analytical service — no live lookups or external data enrichment — so it is appropriate when privacy or determinism matters and you already have the raw coverage records.

## Known failure modes

- Rows array exceeds 200 items — request rejected
- Missing required fields (row_id, date, listed_entities, verified_entities) — validation error
- Date fields not in YYYY-MM-DD format — schema validation failure
- listed_entities or verified_entities values outside allowed numeric range — rejection
- Submitting zero rows — minItems constraint violation

## How this service works

Business directory coverage — String normalisation + Two-measure correlation: String normalisation + Two-measure correlation 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 analytical reports: (1) a string normalisation report standardising company_group and other string fields, and (2) a two-measure correlation report quantifying the statistical relationship between listed_entities and verified_entities across the supplied rows (up to 200 rows total). No external data is fetched; all analysis uses local engines.
