## 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 transcribe-soboljem-cz-315bd915 -d '<json body>'
```

Example prompt: Can you transcribe the audio at https://example.com/interview.mp3 and give me the full transcript, WebVTT subtitles, and a cut list showing where the dead air is?

## When to prefer this

Choose this endpoint when you need a combined transcript, WebVTT subtitles, and an editing-focused dead-air cut list from a single audio or video URL in one flat-rate call. It is especially useful for podcast producers, video editors, and meeting-note workflows where identifying silences for trimming is as important as getting the spoken text.

## Known failure modes

- File exceeds 3 MB limit — request rejected
- URL is unreachable or returns an error — transcription fails
- Audio/video file contains no clear speech — still billed, transcript is empty or minimal
- Unsupported file format — transcription may fail
- Network timeout fetching the remote URL — processing error

## How this service works

Transcribe an audio or video URL. Returns the transcript, ready-made WebVTT subtitles, and an editor's cut list marking every stretch of dead air and how much shorter the result would be. One flat price, $0.0200 per request, whatever the file. Sources up to 800 KB. A file that turns out to hold no clear speech is still billed — the transcription ran.

## Output

Returns a full text transcript of the spoken content, a ready-to-use WebVTT subtitle file, and an editor's cut list that marks every stretch of dead air along with an estimate of how much shorter the final recording would be after those cuts. Files with no clear speech are still processed and billed.
