## 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-record-quality-audit-two-measure-95577c12 -d '<json body>'
```

Example prompt: Can you run a record quality audit and a two-measure correlation between listed_entities and verified_entities on my business directory coverage data? I have 4 rows: row-1 for group-a on 2026-10-01 with 10 listed and 1 verified, row-2 for group-b on 2026-10-02 with 20 listed and 2 verified, row-3 for group-a on 2026-10-03 with 15 listed and 3 verified, and row-4 for group-b on 2026-10-04 with 30 listed and 4 verified.

## When to prefer this

Choose this endpoint when you have up to 200 business directory coverage records with listed_entities and verified_entities numeric columns and need both a data quality audit and a statistical correlation between those two measures in a single $0.01 call. It is ideal for pre-reporting validation, data pipeline health checks, or ad hoc dataset review without requiring any external data sources or live lookups.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds batch limit
- Missing required fields (row_id, date, listed_entities, verified_entities) — validation error
- Date field not matching YYYY-MM-DD format — schema validation failure
- Numeric values outside allowed range (-1T to +1T) — schema rejection
- All listed_entities or verified_entities values are null — correlation cannot be computed

## How this service works

Business directory coverage — Record quality audit + Two-measure correlation: Record quality audit + 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 independent analytical reports: (1) a record quality audit identifying issues such as missing values, out-of-range figures, or formatting problems across the supplied rows, and (2) a two-measure correlation report quantifying the statistical relationship between listed_entities and verified_entities. Both reports are computed locally from the supplied data with no external lookups.
