## 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 citiview-agent-market-premium-audio-video-transcription-deepgram-nova-3-6537f1f7
```

Example prompt: Can you transcribe this podcast episode for me — https://example.com/podcast.mp3 — up to 30 minutes, with speaker labels turned on and word timestamps included?

## When to prefer this

Choose this endpoint when you need high-quality, production-grade transcription of a publicly accessible audio or video file with advanced features like speaker diarization, word timestamps, and automatic language detection — especially when Deepgram Nova-3 quality is desired. Prefer it over generic STT APIs when you need smart punctuation out of the box, optional persistent share links, or per-minute cost control via max_minutes.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns an error indicating the file could not be fetched
- max_minutes set too low for the actual audio length — transcript may be cut off or billed only for specified duration
- Unsupported audio/video format — Deepgram returns a processing error
- Network timeout on very large files — may return a timeout or partial result
- Invalid language code supplied — may fall back to auto-detection or return an error
- Payment insufficient for requested duration — x402 payment required error

## How this service works

Premium transcription with Deepgram Nova-3: smart punctuation and formatting, language detection, optional speaker labels (diarization) and word timestamps, for a public audio or video file. $0.012 per audio minute (set max_minutes), minimum $0.02. Add store=true (+$0.001) to get a 7-day share link instead of the data inline.

## Output

Returns a JSON object containing the full transcript text with smart punctuation and formatting, detected language, optionally per-speaker labeled segments (diarization), optionally word-level timestamps, and if store=true, a 7-day public share link URL instead of inline data.
