We can spin up your own instance of Libre Translate, either on your infrastructure or on ours. Alternatively, you can use our in-house server at translate.wasyaco.com - but please request an API key first.
This is what an API call looks like:
curl -X POST https://translate.wasyaco.com/translate \
-H "Content-Type: application/json" \
-d '{
"q": "Hello, how are you?",
"source": "en",
"target": "es",
"format": "text"
}'.
