# Transcript Preparation: Category Frequencies + Numeric Row Ordering

> Transcript Preparation: Category Frequencies + Numeric Row Ordering is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Analyzes transcript preparation records by computing category frequencies for document_group and sorting rows numerically by transcribed_minutes or source_minutes — returns two analytical reports for up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 transcript-preparation-category-frequencies-numeric-row-ordering-a93f45af -d '<json body>'
```

Example prompt: Analyze my transcript preparation batch — I have 50 rows with document_group and transcribed_minutes fields — and give me both a category frequency breakdown by document group and the rows sorted numerically by transcribed_minutes.

## When to prefer this

Choose this endpoint when you need simultaneous category frequency analysis and numeric row ranking on transcript preparation data (transcribed_minutes, source_minutes) in a single $0.01 call. It is ideal for offline batch analytics on up to 200 records where no live data lookup, external API call, or predictive modeling is required — just fast local computation on supplied data.

## Known failure modes

- Exceeding 200 rows returns an error — batch must be split
- Missing required fields (row_id, document_group, date, transcribed_minutes, source_minutes) cause validation failure
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Numeric values outside ±1,000,000,000,000 are rejected
- Empty rows array (minItems:1 not satisfied) causes rejection

## How this service works

Transcript preparation — Category frequencies + Numeric row ordering: Category frequencies + Numeric row ordering for supplied transcript preparation records (transcribed_minutes, source_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

Two reports: (1) a category frequency table showing how many rows belong to each unique document_group value, and (2) the input rows sorted in numeric order by the selected field (transcribed_minutes or source_minutes). No predictions, external lookups, or professional assessments included.
