## 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 registry-snapshots-record-quality-audit-two-measure-correlation-150b38d3 -d '<json body>'
```

Example prompt: Can you audit the data quality and run a correlation analysis between registered_entities and changed_entities for these registry snapshot rows — I have up to 4 rows across company groups group-a and group-b for dates 2026-10-01 through 2026-10-04?

## When to prefer this

Choose this endpoint when you have up to 200 registry snapshot records with registered_entities and changed_entities counts and need both a structured data quality audit and a correlation analysis in a single low-cost call ($0.01 USDC). It is ideal for offline or batch analytical workflows where no live data lookup, real-time monitoring, or external enrichment is needed — just supplied-data analysis.

## Known failure modes

- Empty rows array or fewer than 1 row submitted — validation error
- More than 200 rows submitted — rejected with max-items error
- Missing required fields (row_id, date, company_group) on any row — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Values outside numeric range limits — rejected by schema
- Insufficient numeric variation in data — correlation may be undefined or return NaN

## How this service works

Registry snapshots — Record quality audit + Two-measure correlation: Record quality audit + Two-measure correlation for supplied registry snapshots records (registered_entities, changed_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 flagging issues such as nulls, out-of-range values, or inconsistencies across the supplied rows, and (2) a two-measure correlation report quantifying the statistical relationship between registered_entities and changed_entities across all provided rows. No external lookups or predictions are made; all analysis is performed locally on the supplied data.
