Create an API key

Make a request

Pick an SDK, request mode, and language. The model and provider route are already filled in.

ElevenLabs SDK streaming TTS

Routes the ElevenLabs SDK through allmodels and streams the audio response.

import { ElevenLabsClient } from "elevenlabs";

const client = new ElevenLabsClient({
  apiKey: process.env.ALLMODELS_API_KEY,
  baseUrl: "https://api.allmodels.io/el"
});

const stream = await client.textToSpeech.stream("voice_id", {
  text: "I'm sorry, Dave. I'm afraid I can't do that.",
  modelId: "elevenlabs/eleven-turbo-v2",
  outputFormat: "mp3_44100_128"
});

const reader = stream.getReader();
for (;;) {
  const { done, value } = await reader.read();
  if (done) break;
  // Write value to your response, file, or audio playback pipeline.
}

Use native SDK parameters

When the selected SDK matches the provider, pass provider parameters as native SDK fields. Provider preferences are only needed for cross-provider SDK usage.

Providers

Different providers can host the same model. Choose one provider when you need a fixed backend, or let routing select among them.
