# Transcript Preparation — Daily Sum Series + Equal-Width Histogram

> Transcript Preparation — Daily Sum Series + 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 2026-10-26).

Computes a daily sum time series and an equal-width histogram for transcribed_minutes or source_minutes fields across up to 200 transcript preparation records.

## 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-daily-sum-series-equal-width-histogram-56fdf166 -d '<json body>'
```

Example prompt: Can you run a daily sum time series and a 5-bin equal-width histogram on my transcript preparation data — I have records with transcribed_minutes and source_minutes for each row, grouped by document group and dated from 2026-10-01 to 2026-10-04, and I want to analyze the transcribed_minutes field?

## When to prefer this

Choose this endpoint when you need both a temporal daily aggregation (sum series) and a frequency distribution (histogram) of transcript preparation metrics — transcribed_minutes or source_minutes — in a single API call, from supplied data up to 200 rows, without requiring any external data sources or live lookups. Ideal for batch reporting on transcription workflows.

## Known failure modes

- More than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) causes row rejection
- bins value outside 1–30 range returns validation error
- Empty rows array returns error
- Unknown field value (not transcribed_minutes or source_minutes) causes validation failure
- All null values for selected field may produce empty or degenerate histogram

## How this service works

Transcript preparation — Daily sum series + Equal-width histogram: Daily sum series + 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 independent analytical reports: (1) a daily sum series showing the total of the selected field (transcribed_minutes or source_minutes) aggregated by date, and (2) an equal-width histogram showing the frequency distribution of values across the specified number of bins (1–30). Both reports are computed locally from the supplied data without any external lookups.
