Get Your API Key

Create a Fish Audio account, generate an API key, and make your first request

Everything you build with Fish Audio (the API, the Python library, JavaScript) authenticates with a single API key. Here’s how to get one and make your first call in a couple of minutes.

1. Create an account and key

1. Sign up

   Go to fish.audio/auth/signup, create an account, and verify your email.

2. Open the API Keys page

   Sign in and open fish.audio/app/api-keys.

3. Create a key

   Click Create New Key, give it a descriptive name (and an expiration if you want), then copy the key and store it securely.

   Never commit your API key to version control or share it publicly.

2. Store it as an environment variable

The SDKs and the examples throughout these docs read your key from FISH_API_KEY:

export FISH_API_KEY="your_api_key_here"

This keeps the key out of your code and lets you use different keys for development and production.

3. Make your first request

Python

from fishaudio import FishAudio
from fishaudio.utils import save

client = FishAudio()  # reads FISH_API_KEY
audio = client.tts.convert(text="Hello from Fish Audio!")
save(audio, "hello.mp3")

You just generated your first audio. Where to next:

Text to Speech

Voices, formats, speed, and streaming.
