## Async TTS with retrieval

### Python

```
import requests
import json

# Step 1: Initiate async TTS
url = "https://api.upliftai.org/v1/synthesis/text-to-speech-async"

payload = json.dumps({
  "voiceId": "v_meklc281",
  "text": "سلام، یہ پاکستان کی تاریخ کے بارے میں ہے۔",
  "outputFormat": "MP3_22050_128"
})
headers = {
  'Content-Type': 'application/json',
  'Authorization': 'Bearer YOUR_API_KEY'
}

response = requests.post(url, headers=headers, data=payload)
result = response.json()

# Step 2: Retrieve audio when ready
media_id = result['mediaId']
token = result['token']

audio_url = f"https://api.upliftai.org/v1/synthesis/stream-audio/{media_id}?token={token}"

# Get the audio
audio_response = requests.get(audio_url)

# Save to file
with open('output.mp3', 'wb') as f:
    f.write(audio_response.content)
```

```javascript
