## 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-list-models-4f244cde -d '<json body>'
```

Example prompt: What speech-to-text and text-to-speech models does Deepgram currently have available, including the Nova-3 and Aura-2 series?

## When to prefer this

Use this endpoint when you need to discover which Deepgram models are available before making a transcription, TTS, or analysis call — especially useful for dynamically selecting the best model or verifying a model ID is valid. Prefer this over hardcoding model names, as Deepgram regularly adds new models like Nova-3 and Aura-2.

## Known failure modes

- Invalid API credentials — authentication error returned
- Network timeout if Deepgram service is unavailable
- Empty response if no models are available in the account tier
- Rate limit exceeded — too many requests in a short period
