# LibreTranslate CPU API on Hugging Face Spaces

This Space runs LibreTranslate as a Docker Space.

## API test

Replace `YOUR_USERNAME` and `YOUR_SPACE_NAME` with your Hugging Face username and Space name.

```bash
curl -X POST "https://YOUR_USERNAME-YOUR_SPACE_NAME.hf.space/translate" \
  -H "Content-Type: application/json" \
  -d '{"q":"Hello friend","source":"en","target":"pl","format":"text"}'
```

Expected response:

```json
{
  "translatedText": "Witaj przyjacielu"
}
```

## Loaded languages

This template loads only these languages to reduce CPU/RAM use:

- English: `en`
- Polish: `pl`
- Russian: `ru`
- Spanish: `es`
- French: `fr`
- German: `de`
- Korean: `ko`

To change this, edit `LT_LOAD_ONLY` in `Dockerfile`.

## Important

Free Hugging Face Spaces can sleep after inactivity. First request after sleep can be slow because LibreTranslate has to start again.
