# Transcript Preparation — Grouped Numeric Summary + Adjacent Row Changes

> Transcript Preparation — Grouped Numeric Summary + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Analyzes transcript preparation records (transcribed_minutes, source_minutes) to produce two local analytical reports: a grouped numeric summary and an adjacent-row change analysis, for up to 200 rows.

## 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-grouped-numeric-summary-adjacent-row-changes-f3daecb1 -d '<json body>'
```

Example prompt: Can you analyze these transcript preparation records for me — I have up to 50 rows with fields like row_id, document_group, date, transcribed_minutes, and source_minutes — and give me both a grouped numeric summary by document_group and the adjacent row changes for the transcribed_minutes field?

## When to prefer this

Choose this endpoint when you have transcript preparation record data (up to 200 rows) and need both a grouped aggregate summary and adjacent row change analysis in a single $0.01 USDC call, without needing live lookups, predictions, or external integrations. Prefer it over general analytics services when working specifically with transcribed_minutes and source_minutes fields organized by document_group and date.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, document_group, date, transcribed_minutes, source_minutes) causes rejection
- Invalid date format (non-YYYY-MM-DD) fails pattern validation
- Numeric values outside the allowed range trigger schema errors
- Empty rows array is rejected (minItems: 1)
- Invalid field enum value (anything other than transcribed_minutes or source_minutes) causes error

## How this service works

Transcript preparation — Grouped numeric summary + Adjacent row changes: Grouped numeric summary + Adjacent row changes 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

Returns two analytical reports computed locally from the supplied data: (1) a grouped numeric summary aggregating transcribed_minutes or source_minutes by document_group (e.g. count, sum, mean, min, max), and (2) an adjacent row changes report showing sequential differences between consecutive rows ordered by date and group, for up to 200 input rows.
