## 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 label-review-record-quality-audit-category-frequencies-8077b6dc -d '<json body>'
```

Example prompt: Can you run a record quality audit and category frequency report on my label review data? I have 4 rows: row-1 for group-a on 2026-10-01 with 10 reviewed records and 1 changed label, row-2 for group-b on 2026-10-02 with 20 reviewed and 2 changed, row-3 for group-a on 2026-10-03 with 15 reviewed and 3 changed, and row-4 for group-b on 2026-10-04 with 30 reviewed and 4 changed.

## When to prefer this

Choose this endpoint when you have up to 200 rows of label review data and need both a record quality audit and category frequency analysis in a single low-cost call ($0.01 USDC). It is ideal for ML/annotation pipelines where you want to assess data integrity and understand label change distributions across dataset groups without any external lookups or live model inference.

## Known failure modes

- Empty rows array or missing required fields (row_id, date, reviewed_records, changed_labels) causes validation error
- More than 200 rows submitted exceeds the batch limit
- Date strings not matching YYYY-MM-DD pattern are rejected
- Numeric values outside the allowed range (-1e12 to 1e12) are rejected
- Null values for reviewed_records or changed_labels may affect audit completeness

## How this service works

Label review — Record quality audit + Category frequencies: Record quality audit + Category frequencies for supplied label review records (reviewed_records, changed_labels). 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 highlighting completeness, anomalies, or issues in the supplied label review rows, and (2) a category frequency analysis showing the distribution of reviewed_records and changed_labels across dataset_group values — all computed locally with no external lookups.
