  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const result = await openRouter.tts.createSpeech({
    speechRequest: {

run();

Standalone function

The standalone function version of this method:
import { OpenRouterCore } from "@openrouter/sdk/core.js";
import { ttsCreateSpeech } from "@openrouter/sdk/funcs/ttsCreateSpeech.js";

// Use `OpenRouterCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const openRouter = new OpenRouterCore({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const res = await ttsCreateSpeech(openRouter, {
    speechRequest: {
      input: "Hello world",
      model: "elevenlabs/eleven-turbo-v2",
      speed: 1,
      voice: "alloy",
    },
  });
  if (res.ok) {
    const { value: result } = res;
    console.log(result);
  } else {
    console.log("ttsCreateSpeech failed:", res.error);
  }
}

run();
