## 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-duplicate-key-report-21290e94 -d '<json body>'
```

Example prompt: Can you run a string normalisation and duplicate key check on my business directory coverage data? I have 4 rows — group-a on 2026-10-01 with 10 listed and 1 verified, group-b on 2026-10-02 with 20 listed and 2 verified, group-a again on 2026-10-03 with 15 listed and 3 verified, and group-b on 2026-10-04 with 30 listed and 4 verified.

## When to prefer this

Choose this endpoint when you need lightweight, offline data-quality checks — specifically string normalisation and duplicate key detection — on batches of business directory coverage records up to 200 rows. It is ideal for pre-import validation workflows where no live external lookup, ML prediction, or third-party enrichment is needed. Prefer it over general-purpose data tools when your data model matches the listed_entities/verified_entities/company_group schema and you need two reports in a single low-cost call.

## Known failure modes

- Submitting more than 200 rows returns a validation error
- Missing required fields (row_id, company_group, date, listed_entities, verified_entities) cause row rejection
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Empty rows array rejected (minItems: 1)
- listed_entities or verified_entities values outside ±1,000,000,000,000 are rejected
- Payment failure results in 402 response with no report generated

## How this service works

Business directory coverage — String normalisation + Duplicate key report: String normalisation + Duplicate key report 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 for the submitted rows: (1) a string normalisation report identifying inconsistencies in string fields such as company_group names, and (2) a duplicate key report flagging rows with repeated row_id or company_group/date combinations. No external lookups or predictions are made — all analysis is performed locally on the supplied data.
