Step-by-Step Migration

1

Get Your Murf API Key

Sign up at Murf API Dashboard and generate your API key. Store it securely as an environment variable if needed.

2

Test Connectivity

Verify your API key works with a simple request: bash curl -X GET https://api.murf.ai/v1/speech/voices \ -H "api-key: YOUR_API_KEY"

3

API Endpoint Migration

Change the API endpoint to Murf’s.

Play.ai Endpoint:

POST https://api.play.ai/api/v1/tts/stream

Murf Endpoint:

POST https://api.murf.ai/v1/speech/stream
4

Authentication Changes

Play.ai uses X-USER-ID and Authorization headers for authentication. Murf uses api-key header. Make sure to update your code to use the new header.

const headers = {
'X-USER-ID': 'your-user-id',
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json'
};
5

Request Body Parameter Mapping

Change the request body parameters to match Murf’s parameters. Only text, and voiceId are the required parameters and all other parameters are optional.

Play.ai ParameterMurf ParameterNotes
texttextDirect mapping, no need to change
voicevoiceIdUse a murf voice ID, you can choose from here
output_formatformat”MP3”, “WAV”, or “PCM”
sample_ratesampleRate8000, 24000, 44100, or 48000
speedrateRange: -50 to +50 (vs Play.ai’s decimal values)

Any other Play.ai parameter that was not listed above should be removed. To see the full list of parameters that you can use, please refer to the Murf Streaming API Reference.

Process the Response

Both Play.ai and Murf return the audio stream in the response body. You can use the same code to process the response.

Code Migration Examples

import requests
url = "https://api.play.ai/api/v1/tts/stream"
headers = {
    "X-USER-ID": "your-user-id",
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}
data = {
    "text": "Hello, this is a test message.",
    "voice": "s3://voice-cloning-zero-shot/path/to/voice",
    "voice_engine": "Play3.0",
    "output_format": "mp3",
    "sample_rate": 44100,
    "speed": 1.0
}
response = requests.post(url, headers=headers, json=data, stream=True)
with open("audio.mp3", "wb") as f:
    for chunk in response.iter_content(chunk_size=1024):
        f.write(chunk)

Voice Migration Guide

Finding Equivalent Voices

Play.ai used complex S3 paths for voice selection. Murf uses intuitive voice names and IDs.

Play.ai Voice Examples:

s3://voice-cloning-zero-shot/d9ff78ba-d016-47f6-b0ef-dd630f59414e/female-cs/manifest.json

Murf Voice Examples:

"en-US-natalie"     // Female, US English
"en-UK-oliver"      // Male, UK English
"es-ES-sofia"       // Female, Spanish
"fr-FR-marcel"      // Male, French
Voice Library

Use our Voice Library to find the perfect voice for your needs.

To programmatically fetch the list of voices, use the List voices endpoint.

from murf import Murf
client = Murf(api_key="YOUR_API_KEY")
voices = client.voices.list()
for voice in voices:
    print(f"{voice.voice_id} - {voice.display_name} ({voice.gender})")
