## 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 interview-transcripts-adjacent-row-changes-date-by-category-pivot-933f4275 -d '<json body>'
```

Example prompt: I have 4 interview transcript records with word counts and audio minutes — can you run adjacent row change analysis and a date-by-category pivot on them? The rows are: row-1 on 2026-10-01 in group-a with 10 words and 1 minute, row-2 on 2026-10-02 in group-b with 20 words and 2 minutes, row-3 on 2026-10-03 in group-a with 15 words and 3 minutes, and row-4 on 2026-10-04 in group-b with 30 words and 4 minutes — use transcript_words as the field.

## When to prefer this

Choose this endpoint when you have interview transcript records with word counts and audio duration and need both sequential (row-over-row) change analysis and a date-by-category pivot in a single low-cost call. It is ideal for offline/batch analytical workflows on pre-collected data with no need for live lookup or real-time enrichment. Best suited when your dataset is up to 200 rows and you want two complementary reports — trend and pivot — at once.

## Known failure modes

- Missing required fields (row_id, channel_group, date, transcript_words, audio_minutes) returns a validation error
- Date values not matching YYYY-MM-DD format are rejected
- Submitting more than 200 rows exceeds the row limit and is rejected
- Submitting fewer than 1 row returns a validation error
- Null values in the selected metric field may produce null or skipped entries in the change calculations

## How this service works

Interview transcripts — Adjacent row changes + Date by category pivot: Adjacent row changes + Date by category pivot for supplied interview transcripts records (transcript_words, audio_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 analytical reports: (1) an adjacent row changes table showing sequential differences in the selected metric (transcript_words or audio_minutes) between consecutive records; and (2) a date-by-category pivot table aggregating the selected metric across channel groups by date. Both reports are computed locally from the supplied rows with no external data access.
