## 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-medienwerk-speaker-time-90a55af5 -d '<json body>'
```

Example prompt: Take this meeting recording at https://example.com/meeting.mp3 and tell me who spoke when — I need each speaker's turns with timestamps so I can see how long each participant talked.

## When to prefer this

Choose this endpoint when you need speaker-level segmentation of a multi-participant audio or video file with precise timestamps per turn. It is ideal for meeting transcripts, podcast editing, legal recordings, or call center analytics where knowing who spoke when matters more than (or in addition to) what was said. Prefer this over a pure transcription endpoint when speaker attribution is the primary goal.
