# Transcript Preparation — Duplicate Key Report + Equal-Width Histogram

> Transcript Preparation — Duplicate Key Report + Equal-Width Histogram 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 transcript preparation records to detect duplicate row_id keys and produce an equal-width histogram over transcribed_minutes or source_minutes, returning two independent analytical reports 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-duplicate-key-report-equal-width-histogram-471e9f4b -d '<json body>'
```

Example prompt: Can you check my transcript prep records for duplicate row IDs and also generate a 10-bin equal-width histogram on the transcribed_minutes field? Here are my rows: row-1 (group-a, 2026-10-01, transcribed=45, source=60), row-2 (group-b, 2026-10-02, transcribed=30, source=40), row-1 (group-a, 2026-10-03, transcribed=55, source=70).

## When to prefer this

Choose this endpoint when you need both a duplicate key audit and a numeric distribution histogram for transcript preparation data (transcribed_minutes, source_minutes) in a single low-cost call. It is ideal for pre-ingestion data quality checks on batches up to 200 rows where no external lookups or live data are required. Prefer it over general-purpose analytics tools when cost, speed, and schema-specific transcript fields matter.

## Known failure modes

- Submitting more than 200 rows returns a validation error
- Missing required fields (row_id, date, transcribed_minutes, source_minutes) causes row-level rejection
- Invalid date format (not YYYY-MM-DD) fails schema validation
- Bins parameter outside 1–30 range is rejected
- Selecting a field not in the enum ('transcribed_minutes','source_minutes') causes an error
- Empty rows array returns an error

## How this service works

Transcript preparation — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram 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 reports: (1) a duplicate key report listing any row_ids that appear more than once across the submitted rows, and (2) an equal-width histogram over the selected numeric field (transcribed_minutes or source_minutes) divided into the specified number of bins, showing bin ranges and counts. Both reports are computed locally from the supplied data with no external lookups.
