## Tools

### Get Model by ID

**Slug:** `DEEPGRAM_GET_MODEL`

Retrieve metadata for a specific Deepgram model by its UUID. Returns detailed model information including name, architecture, supported languages, version, and capabilities. Works for both STT (speech-to-text) and TTS (text-to-speech) models.

### Get Public Models

**Slug:** `DEEPGRAM_GET_MODELS`

Retrieve metadata on all public Deepgram models (speech-to-text and text-to-speech). Returns comprehensive model information including supported languages, architectures, versions, and capabilities. Set include_outdated to True to include deprecated versions.

### List Deepgram Projects

**Slug:** `DEEPGRAM_GET_PROJECTS`

Tool to list all Deepgram projects. Use after authenticating with your API key.

### Get Project Usage Summary

**Slug:** `DEEPGRAM_GET_PROJECT_USAGE_SUMMARY`

Retrieves aggregated usage statistics for a Deepgram project including total audio duration, billable duration, number of requests, channels processed, and confidence/relevance scores. Returns both overall totals and breakdowns by model/accessor/tag. Use this to analyze API consumption, track costs, or monitor transcription quality metrics over time.

### List Project Scopes

**Slug:** `DEEPGRAM_LIST_PROJECT_SCOPES`

Tool to list all scopes for a specified Deepgram project. Use when you need to retrieve all permission scopes for a project.

### List Think Models

**Slug:** `DEEPGRAM_LIST_THINK_MODELS`

Tool to list available think models for AI agent processing and voice agent configuration. Use when you need to see which think models are available for voice agents.

### Transcribe Pre-recorded Audio

**Slug:** `DEEPGRAM_SPEECH_TO_TEXT_PRE_RECORDED`

Tool to transcribe pre-recorded audio files into text. Use when converting a publicly accessible audio file URL to text. Primary transcript is at `results.channels[0].alternatives[0].transcript` in the response. Silent audio returns a valid empty transcript, not an error. Verify supported models and language codes via `DEEPGRAM_GET_MODELS` when uncertain.

### Text-to-Speech (REST)

**Slug:** `DEEPGRAM_TEXT_TO_SPEECH_REST`

Tool to convert text into natural-sounding speech. Use when you need TTS audio from text inputs.
