API Examples

Request:

const res = await fetch("https://libretranslate.com/translate", {
	method: "POST",
	body: JSON.stringify({
		q: "Hello!",
		source: "en",
		target: "es"
	}),
	headers: { "Content-Type": "application/json" }
});

console.log(await res.json());

Response:

{
    "translatedText": "¡Hola!"
}

Build and Run

You can run your own API server in just a few lines of setup!

Make sure you have installed Python (3.8 or higher), then simply issue:

git clone https://github.com/uav4geo/LibreTranslate --recurse-submodules
cd LibreTranslate
pip install -r requirements.txt
python main.py [args]

Then open a web browser to http://localhost:5000

Run with Docker

Simply run:

docker run -ti --rm -p 5000:5000 libretranslate/libretranslate

Then open a web browser to http://localhost:5000

Build with Docker

Make sure you cloned the models submodule before building the Docker image:

docker build -t libretranslate .

Run the built image:

docker run -it -p 5000:5000 libretranslate [args]

Or build and run using docker-compose:

docker-compose up -d --build

Feel free to change the docker-compose.yml file to adapt it to your deployment needs, or use an extra docker-compose.prod.yml file for your deployment configuration.

FAQ

Can I use your API server at libretranslate.com for my application in production?

The API on libretranslate.com should be used for testing, personal or infrequent use. If you're going to run an application in production, please get in touch to discuss options.

This work is largely possible thanks to Argos Translate, which powers the translation engine.
