## 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 third-party-reviews-category-frequencies-numeric-row-ordering-fb46aebd -d '<json body>'
```

Example prompt: I have a set of third-party vendor review records with control groups, dates, vendors_reviewed, and outstanding_actions — can you run category frequency counts across control groups and also rank the rows by vendors_reviewed for up to 200 rows?

## When to prefer this

Choose this endpoint when you have tabular third-party review data with categorical grouping and numeric metrics and need both a category frequency distribution and a numeric row ranking in a single low-cost call. Ideal for vendor risk tracking, procurement review audits, or any workflow where you need to understand control group distributions and prioritize rows by a numeric field without requiring live lookups or predictions.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, control_group, date, vendors_reviewed, outstanding_actions) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema validation failure
- Numeric values outside allowed range (-1T to 1T) — rejection
- Empty rows array — minimum 1 item required
- Invalid field enum value — must be vendors_reviewed or outstanding_actions

## How this service works

Third party reviews — Category frequencies + Numeric row ordering: Category frequencies + Numeric row ordering for supplied third party reviews records (vendors_reviewed, outstanding_actions). 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 analytical reports: (1) a category frequency table showing how often each control_group value appears in the supplied rows, and (2) a numerically ordered ranking of all rows sorted by the selected field (vendors_reviewed or outstanding_actions). Covers up to 200 input rows with no external lookups or predictions.
