# Transcript Preparation: Adjacent Row Changes + Two-Measure Correlation

> Transcript Preparation: Adjacent Row Changes + Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Analyzes up to 200 transcript preparation records by computing adjacent row changes and two-measure correlation between transcribed_minutes and source_minutes.

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-adjacent-row-changes-two-measure-correlation-61ff3f5a -d '<json body>'
```

Example prompt: I have 150 transcript preparation records with transcribed_minutes and source_minutes across several document groups — can you run both an adjacent row changes analysis and a two-measure correlation report on the transcribed_minutes field for me?

## When to prefer this

Use this endpoint when you have structured transcript preparation data with both transcribed_minutes and source_minutes fields and need both a sequential change analysis and a correlation analysis in a single low-cost call. Ideal for batch audits of transcription pipelines, quality reviews, or volume trend analysis where no live lookup or external data enrichment is needed.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, transcribed_minutes, source_minutes) cause validation error
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- All null values in the selected metric field prevent meaningful computation
- Non-numeric values in transcribed_minutes or source_minutes fail schema validation

## How this service works

Transcript preparation — Adjacent row changes + Two-measure correlation: Adjacent row changes + Two-measure correlation 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 for the supplied rows: (1) an adjacent row changes report showing how transcribed_minutes or source_minutes shift between consecutive rows, and (2) a two-measure correlation report quantifying the statistical relationship between transcribed_minutes and source_minutes across all supplied records.
