import express from "express";
const app = express();

app.post("/voice/session", async (req, res) => {
  const { channelName } = req.body;
  const r = await fetch(process.env.DNZ_VOICE_API_URL + "/v1/channels", {
    method: "POST",
    headers: {
      Authorization: "Bearer " + process.env.DNZ_VOICE_API_KEY,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({ channelName, maxPeers: 30, mode: "open" }),

  if (r.status === 402) return res.status(402).json({ error: "quota_exceeded" });
  const data = await r.json();
  res.json(data);

    {
      method: "POST",
      headers: {
        Authorization: "Bearer " + process.env.DNZ_VOICE_API_KEY,
