# List voice providers

> Returns metadata for every supported TTS / voice provider including capabilities, available models and the workspace secret key used.

Use this endpoint to power a "Choose a voice provider" UI. Each provider entry tells you:

* `displayName` & `iconUrl` — for rendering provider chips/cards
* `requiresWorkspaceApiKey` — `true` if the provider has no platform fallback (the workspace must save its own API key under `workspaceSecretKey`)
* `workspaceSecretKey` — name of the field under `workspaceData.secrets.*` to persist the API key (e.g. `ELEVENLABS_API_KEY`)
* `capabilities` — booleans for `speed`, `volume`, `emotion`, `modelId`, `sampleText`, `customVoiceCloning`
* `models` — built-in model IDs you can pass to `/voices` and `/voices/{provider}` via `?modelId=`

<Tip>
  This endpoint is a utility helper — it does **not** consume credits and never proxies provider APIs.
