## 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-density-analysis-1e491f19 -d '<json body>'
```

Example prompt: Can you analyze this podcast episode recording at https://example.com/episode.mp3 and tell me the speaker density — how many distinct speakers there are and what percentage of the total speaking time each one takes up?

## When to prefer this

Choose this endpoint when you need to quantify how many distinct speakers are present in a media file and how speaking time is distributed among them — particularly useful for podcast production QA, interview fairness audits, panel discussion analytics, or media compliance checks. Prefer over generic transcription endpoints when you need speaker proportions rather than word-level content.

## Known failure modes

- Unreachable or invalid media URL returns an error
- Unsupported audio/video codec or format may cause processing failure
- Single-speaker content may report density of 1 with 100% attribution
- Very noisy or low-quality audio may reduce speaker detection accuracy
- Overlapping speech may cause undercounting of distinct speakers
- Large files may time out if not delivered via fast CDN
