import { GladiaSTT } from '@micdrop/gladia'
import { ElevenLabsTTS } from '@micdrop/elevenlabs'
import Fastify from 'fastify'

const fastify = Fastify({ logger: true })

// Register WebSocket support
await fastify.register(import('@fastify/websocket'))

// WebSocket route for voice calls
fastify.register(async function (fastify) {
  fastify.get('/call', { websocket: true }, (connection, request) => {
    // Setup AI components
    const agent = new OpenaiAgent({
      apiKey: process.env.OPENAI_API_KEY || '',
