## 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 halowerk-buerowerk-decision-source-timeline-81327657 -d '<json body>'
```

Example prompt: I have a transcript of our 45-minute product planning meeting — can you analyze it and give me a chronological timeline showing which decisions were made, when they happened, and who was the source of each decision?

## When to prefer this

Choose this endpoint when you need structured, speaker-attributed decision timelines extracted from meeting transcripts with precise timestamps. It is purpose-built for meeting intelligence workflows where identifying who decided what and when is the primary goal, as opposed to general summarization or sentiment analysis tools.

## Known failure modes

- Missing required segment fields (start, end, speaker, text) returns a validation error
- Segment timestamps outside allowed range (>14400 seconds) are rejected
- Empty segments array or exceeding 20000-item limit causes schema validation failure
- Ambiguous or null speaker labels may reduce attribution accuracy in the timeline
- Transcript text exceeding 3000 characters per segment is rejected
