# Transcript Preparation — Adjacent Row Changes + Secondary-Measure Weighted Mean

> Transcript Preparation — Adjacent Row Changes + Secondary-Measure Weighted Mean 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).

Computes adjacent row changes and secondary-measure weighted mean for transcript preparation records (transcribed_minutes, source_minutes) across up to 200 rows, returning two analytical reports.

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-secondary-measure-eeaf1439 -d '<json body>'
```

Example prompt: Can you run adjacent row change analysis and a source-minutes weighted mean on my transcript batch? Here are 4 records: row-1 on 2026-10-01 in group-a with source_minutes=1 and transcribed_minutes=10, row-2 on 2026-10-02 in group-b with source_minutes=2 and transcribed_minutes=20, row-3 on 2026-10-03 in group-a with source_minutes=3 and transcribed_minutes=15, row-4 on 2026-10-04 in group-b with source_minutes=4 and transcribed_minutes=30 — use transcribed_minutes as the primary field.

## When to prefer this

Choose this endpoint when you need both sequential delta analysis (how values change row-to-row) and a weighted mean computation on transcript preparation data in a single low-cost call. It is purpose-built for transcribed_minutes and source_minutes fields, making it ideal for transcription workflow analytics, billing reconciliation, and throughput auditing — without requiring any external data sources or live lookups.

## Known failure modes

- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (row_id, date, transcribed_minutes, source_minutes) causes validation failure
- Invalid date format (must match YYYY-MM-DD pattern) results in rejection
- Null values in both primary and secondary measure fields may produce undefined weighted mean
- row_id or document_group exceeding 80 characters triggers schema violation
- Payment not included or insufficient USDC triggers x402 payment-required response

## How this service works

Transcript preparation — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean 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: (1) an adjacent row changes report showing differences in the selected field (transcribed_minutes or source_minutes) between consecutive rows, and (2) a secondary-measure weighted mean report using the complementary field as the weight. Both reports cover up to 200 supplied rows and are computed locally without external lookups.
