# Transcript Preparation — Two-Measure Correlation + Keyed Dataset Comparison

> Transcript Preparation — Two-Measure Correlation + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Computes Pearson/statistical correlation between transcribed_minutes and source_minutes, plus a keyed comparison between two supplied datasets, across up to 200 transcript preparation 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-two-measure-correlation-keyed-dataset-comparison-78bf3416 -d '<json body>'
```

Example prompt: I have two sets of transcript records — each with row IDs, document groups, dates, transcribed_minutes, and source_minutes — and I want to see a correlation report between the two duration fields plus a keyed comparison between the two datasets, up to 200 rows each.

## When to prefer this

Choose this endpoint when you need both a statistical correlation between two numeric duration fields and a record-level keyed comparison between two datasets in a single call, specifically for transcript preparation data (transcribed_minutes vs source_minutes). It is well-suited for quality auditing, vendor comparison, or pipeline validation scenarios involving up to 200 rows. Prefer alternatives if you need more than 200 rows, live data lookups, predictions, or single-report-only analysis.

## Known failure modes

- Fewer than 1 row submitted — request rejected
- More than 200 rows in either dataset — exceeds row limit
- Missing required fields (row_id, date, transcribed_minutes, source_minutes) — validation error
- Date format not matching YYYY-MM-DD pattern — schema validation failure
- Non-numeric values in transcribed_minutes or source_minutes — type error
- Payment not provided or insufficient USDC — 402 Payment Required response
- Mismatched row counts between primary and comparison dataset may reduce keyed comparison coverage

## How this service works

Transcript preparation — Two-measure correlation + Keyed dataset comparison: Two-measure correlation + Keyed dataset comparison 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 independent analytical reports: (1) a two-measure correlation report quantifying the statistical relationship between transcribed_minutes and source_minutes across all supplied rows; (2) a keyed dataset comparison report that matches rows from both input datasets by key and highlights differences. Both reports are computed locally from the supplied data with no external lookups.
