Example Code

import requests

# Define what you want to say and how you want it said
tts_payload = {
    "text": "Jupiter, the largest planet in our solar system, is a gas giant with swirling storms like the iconic Great Red Spot.",
    "voice_id": 123,    # Replace with your chosen voice ID
    "language": 1,      # English
    "output_format": "wav"  # Choose your preferred audio format
}

# Set up your API credentials
headers = {
    "x-api-key": "your-api-key",  # Replace with your actual API key
}

# Make the request with streaming enabled
response = requests.post(
    "https://client.camb.ai/apis/tts-stream",
    json=tts_payload,
    headers=headers,
    stream=True  # This tells requests to stream the response
)

# Check if the request was successful
response.raise_for_status()

# Get the credit usage information (optional)
credits_used = response.headers.get('X-Credits-Required', 'Not specified')
print(f"Credits required for this request: {credits_used}")

# Save the streaming audio to a file
with open("output.wav", "wb") as audio_file:
    # Process the response in chunks to handle large audio files efficiently
    for chunk in response.iter_content(chunk_size=1024):
        if chunk:  # Filter out keep-alive chunks
            audio_file.write(chunk)

print("Voice generation complete! Audio saved as 'output.wav'")
The streaming approach gives you immediate access to your audio, making it perfect for interactive applications, voice assistants, and real-time communication tools. By using the standard requests library with stream=True, you can handle audio generation efficiently even for longer text passages.
