# Use Eleven V3 with Comfy Router

> Call elevenlabs/eleven_v3 through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for `elevenlabs/eleven_v3`, served by Comfy Router from Elevenlabs.

## Quick start

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

**Model ID:** `elevenlabs/eleven_v3`

**Endpoint:** `POST https://api.comfy.org/v2/models/elevenlabs/eleven_v3`

<CodeGroup>
  ```python Python theme={null}
  from comfy_sdk import Comfy

  # Reads COMFY_API_KEY from the environment. Each call sends a fresh
  # Idempotency-Key and waits up to 10 minutes for the finished result.
  with Comfy() as client:
      result = client.models.run(
          "elevenlabs/eleven_v3",
          {
              "inputs": [
                  {
                      "text": "Hello from Comfy Router.",
                      "voice_id": "21m00Tcm4TlvDq8ikWAM",
                  },
              ],
          },
      )

  print(result)
  ```

  ```typescript TypeScript theme={null}
  import { comfy } from "@comfyorg/sdk";

  // Reads COMFY_API_KEY from the environment. Each call sends a fresh
  // Idempotency-Key and waits up to 10 minutes for the finished result.
  const { data } = await comfy.models.run("elevenlabs/eleven_v3", {
    inputs: [
      {
        text: "Hello from Comfy Router.",
        voice_id: "21m00Tcm4TlvDq8ikWAM",
      },
    ],
  });

  console.log(data);
  ```

  ```bash cURL theme={null}
  curl https://api.comfy.org/v2/models/elevenlabs/eleven_v3 \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $(uuidgen)" \
    -H "Content-Type: application/json" \
    -d "{\"inputs\": [{\"text\":\"Hello from Comfy Router.\",\"voice_id\":\"21m00Tcm4TlvDq8ikWAM\"}]}"
  ```

## Schema

### Input

<ParamField body="apply_text_normalization" type="string" default="&#x22;auto&#x22;">
  Controls text normalization with three modes:
  'auto' - system automatically decides whether to apply text normalization
  'on' - text normalization will always be applied
  'off' - text normalization will be skipped

  Possible values: `auto`, `on`, `off`
</ParamField>

<ParamField body="inputs" type="object[]" required>
  A list of dialogue inputs, each containing text and a voice ID which will be converted into speech.
  The maximum number of unique voice IDs is 10.
</ParamField>

<ParamField body="inputs[].text" type="string" required>
  The text to be converted into speech.
</ParamField>

<ParamField body="inputs[].voice_id" type="string" required>
  The ID of the voice to be used for the generation.
</ParamField>

<ParamField body="language_code" type="string">
  Language code (ISO 639-1) used to enforce a language for the model and text normalization.
  If the model does not support provided language code, an error will be returned.
</ParamField>

<ParamField body="model_id" type="string">
  Identifier of the model that will be used. This route admits
  'eleven\_v3' and nothing else; any other value is rejected with 400
  before the request reaches ElevenLabs.
  The upstream ElevenLabs advice to query GET /v1/models for the
  available set does NOT describe this route, which serves one model.
  It is NOT in this schema's `required` list because Comfy Router
  fills it from the `{model}` path segment of
  /v2/models/elevenlabs/\{model}, so a Router caller omits it.
</ParamField>

<ParamField body="pronunciation_dictionary_locators" type="object[]">
  A list of pronunciation dictionary locators (id, version\_id) to be applied to the text.
  They will be applied in order. You may have up to 3 locators per request.
</ParamField>

<ParamField body="pronunciation_dictionary_locators[].pronunciation_dictionary_id" type="string" required>
  The ID of the pronunciation dictionary
</ParamField>

<ParamField body="pronunciation_dictionary_locators[].version_id" type="string" required>
  The version ID of the pronunciation dictionary
</ParamField>

<ParamField body="seed" type="integer">
  If specified, our system will make a best effort to sample deterministically.
  Repeated requests with the same seed and parameters should return the same result.
  Must be integer between 0 and 4294967295.

  Range: `0` to `4294967295`
</ParamField>

<ParamField body="settings" type="object">
  Settings controlling the dialogue generation
</ParamField>

<ParamField body="settings.stability" type="number" default="0.5">
  Determines how stable the voice is and the randomness between each generation.
  Lower values introduce broader emotional range for the voice.
  Higher values can result in a monotonous voice with limited emotion.

  Format: `double`
</ParamField>

Generated from the schema Router serves at `GET /v2/models/elevenlabs/eleven_v3/openapi.json`, the same document it validates a call against before the request reaches the provider.

### Output

Router does not publish an output schema for this model.

## Examples

### Input

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

## Before you ship

The snippets above are the shortest working call. Three things are the same for every model and are documented once on the [Comfy Router headers](/development/comfy-router/headers) page: send an `Idempotency-Key` on every paid call and reuse it when you retry, expect the connection to be held up to Router's 10 minute deadline, and keep `X-Comfy-Request-Id` from every response. The SDKs do all three for you; the cURL tab does none of them. On failure, `X-Comfy-Error-Type` names the bucket, and a `422` means the body failed the model's schema and was never billed.
