# Use Eleven Multilingual V2 with Comfy Router

> Call elevenlabs/eleven_multilingual_v2 through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for `elevenlabs/eleven_multilingual_v2`, served by Comfy Router from Elevenlabs.

**Input:** Text · **Output:** Audio

## Quick start

Create a key in [your Comfy workspace](https://platform.comfy.org/profile/api-keys?onboarding=router) and export it as `COMFY_API_KEY`. The Python and TypeScript snippets use the Comfy SDKs (`pip install comfy-sdk` and `npm install @comfyorg/sdk`); the cURL snippet is the same call over raw HTTP.

**Model ID:** `elevenlabs/eleven_multilingual_v2`

**Endpoint:** `POST https://api.comfy.org/v2/models/elevenlabs/eleven_multilingual_v2`

      # Reads COMFY_API_KEY from the environment.
      # The SDK automatically creates an idempotency key and reuses it for automatic retries.

  <Tab title="Queue and collect later">
    The same body, sent to `POST https://api.comfy.org/v2/models/elevenlabs/eleven_multilingual_v2/requests`. Router answers `201` with a `request_id` as soon as the run is admitted, and the result is collected once it is ready, from this process or another one. [Queued delivery](/development/comfy-router/queue) walks through status, cancellation and collection.

</ParamField>

Generated from the schema Router serves at `GET /v2/models/elevenlabs/eleven_multilingual_v2/openapi.json`, the same document it validates a call against before the request reaches the provider.

### Output

<ResponseField name="*/*" type="string (binary)">
  Raw audio bytes. The Content-Type and encoding follow the requested output\_format and are forwarded from ElevenLabs. The example is a placeholder for the binary body, not JSON or base64.
</ResponseField>

## Examples

### Input

```json theme={null}
{
  "text": "Hello from Comfy Router.",
  "voice_id": "21m00Tcm4TlvDq8ikWAM"
}
```

### Output

Binary body: raw bytes rather than a JSON document, returned as `*/*`, so there is no JSON example to show. The response `Content-Type` and encoding follow the request, as the Output schema above describes.

## Before you ship

The SDKs create an `Idempotency-Key` and reuse it for automatic retries. For manual retries, reuse the original key. Router can hold the connection for up to 10 minutes.

When a request fails, Router sends an `X-Comfy-Error-Type` response header explaining why. A `422` means Router rejected the input before calling the provider, and a `413` means the request body was larger than Router accepts. Download generated assets promptly because [result URLs can expire](/development/comfy-router/reference#result-assets).

Any size limit named in a field description above is the provider's own bound on that field, quoted from the provider's specification. Router applies a separate cap to the whole request body, which base64-encoded media counts against: see [request body size](/development/comfy-router/limitations#request-bodies-are-capped).

This page documents one partner model called through Comfy Router. The same `comfy-sdk` / `@comfyorg/sdk` package also ships a second client, for running a whole ComfyUI workflow graph on Comfy Cloud: `Comfy(api_key=...)` / `new Comfy({ apiKey })`, with `client.workflows`, `client.assets` and `client.jobs`. See [Comfy SDKs](/development/api-development/sdks).
