Error using Translate File function by passing API Key.

Result the URL given by the JSON field translatedFileUrl can't be downloaded (give rate limited)

Example :

http://libretranslate.exemple.com/download_file/102ecxd8-0849-48a9-aa42-9ef2e98a7f54.thefile_en.pdf

{"error":"Ralentissement : 0 per 1 minute"}

And deeper, the problem is something like the LT_API_KEYS_RESTRICTED function is missing ?
