## 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-numeric-distribution-4748b1d1 -d '<json body>'
```

Example prompt: Can you run a string normalisation and numeric distribution analysis on my business directory coverage data? Here are up to 200 rows with row IDs, company groups, dates, listed_entities counts, and verified_entities counts — I want both reports using the listed_entities field.

## When to prefer this

Choose this endpoint when you need fast, local-only statistical profiling of business directory coverage data — specifically string normalisation and numeric distribution reports — on up to 200 rows, without any external lookup, live data fetch, or prediction. It is cost-effective at $0.01 USDC for two reports and is ideal for quick data quality checks or distribution audits on directory coverage metrics.

## Known failure modes

- Fewer than 1 row submitted returns a validation error
- More than 200 rows submitted exceeds the row limit and will be rejected
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) causes schema validation failure
- Dates not matching YYYY-MM-DD pattern are rejected
- Numeric values outside ±1,000,000,000,000 are rejected
- Invalid field enum value (not 'listed_entities' or 'verified_entities') causes error

## How this service works

Business directory coverage — String normalisation + Numeric distribution: String normalisation + Numeric distribution 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

Two independent analytical reports: (1) a string normalisation report covering the selected field's text/category values across all submitted rows, and (2) a numeric distribution report showing statistical spread, counts, and distribution characteristics of the numeric listed_entities or verified_entities field — all computed locally without any external lookup or live data.
