## 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 deepgram-transcribe-beabf3ab -d '<json body>'
```

Example prompt: Transcribe this audio file for me — https://example.com/meeting.mp3 — and turn on smart formatting, speaker diarization, and a summary so I can see who said what and what the meeting was about.

## When to prefer this

Choose this endpoint when you need to convert spoken audio from a publicly accessible URL into text, especially when you also need enrichments like speaker identification, sentiment detection, topic extraction, intents, entity recognition, or a summary in a single call. Prefer Deepgram's Nova-3 model for state-of-the-art accuracy on English audio. Use this over generic alternatives when you need a rich, structured transcription output beyond plain text.

## Known failure modes

- Audio URL is not publicly accessible — returns an error indicating the file could not be fetched
- Unsupported audio format — returns an error about the file type
- Invalid language code — may fall back to default or return a validation error
- Unsupported model name — returns a 400 error with invalid model
- Audio file too large or too long — may time out or return a size limit error
- Network timeout fetching the remote audio URL

## How this service works

Transcribe a pre-recorded audio file from a public URL using Deepgram Nova-3 (default). Returns the full transcript with optional enrichments: punctuation, speaker diarization, smart formatting, paragraphs, sentiment, summary, topics, intents, and entity detection.

## Output

A structured response containing the full transcript text, optionally formatted with punctuation and paragraphs, speaker-labeled segments if diarization was requested, detected sentiment, topics, intents, a summary, and/or named entities depending on which optional features were enabled.
