This example assumes using NariLabs; is in scope and apiKey contains your NariLabs API key.

using var client = new NariLabsClient(apiKey);

var voices = await client.Voices.ListVoicesAsync(model: "qwen3-tts:free");
var voice = voices.Data.First();

// Generate complete WAV audio. The free model can be replaced with
// SpeechRequestModel.Qwen3Tts for the paid Standard endpoint.
var audio = await client.Speech.GenerateSpeechAsync(
    model: SpeechRequestModel.Qwen3Tts_free,
    input: "Hello from the Nari Labs .NET SDK!",
    voice: voice.Id,
    responseFormat: SpeechRequestResponseFormat.Wav);
