## 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 validator-uptime-record-quality-audit-and-two-measure-correlation-6b6b467c -d '<json body>'
```

Example prompt: Can you run a record quality audit and two-measure correlation on my validator uptime data? I have 4 rows: row-1 for group-a on 2026-10-01 with online_minutes=10 and observed_minutes=1, row-2 for group-b on 2026-10-02 with online_minutes=20 and observed_minutes=2, row-3 for group-a on 2026-10-03 with online_minutes=15 and observed_minutes=3, and row-4 for group-b on 2026-10-04 with online_minutes=30 and observed_minutes=4.

## When to prefer this

Choose this endpoint when you need offline, deterministic data quality auditing and correlation analysis on validator uptime records without any live data lookup or prediction. It is ideal when you already have uptime data (online_minutes, observed_minutes) and want a structured quality report plus a statistical correlation measure in a single low-cost call covering up to 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected with validation error
- Missing required fields (row_id, date, online_minutes, observed_minutes, instrument_group) — row rejected or flagged
- Date field not in YYYY-MM-DD format — parsing error or row flagged as invalid
- All rows have null values for one measure — correlation cannot be computed
- Empty rows array — request fails validation

## How this service works

Validator uptime — Record quality audit + Two-measure correlation: Record quality audit + Two-measure correlation for supplied validator uptime records (online_minutes, observed_minutes). 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 missing values, anomalies, or malformed entries across the supplied rows, and (2) a two-measure correlation analysis quantifying the statistical relationship between online_minutes and observed_minutes. Both reports are computed locally with no external lookups.
