You can try GroupDocs.Translation Cloud without subscribing for a paid plan and even without creating an account at GroupDocs Cloud API. The following translation methods are available for free:

Method	Limitations
Translate text	Maximum 1,000 characters (including spaces and line breaks)
Translate Microsoft Word document	Maximum 1,000 characters (including spaces) or the first page (whichever less). Conversion to other formats is not supported.
Translate PDF document	Maximum 1,000 characters (including spaces) or the first page (whichever less). Conversion to other formats is not supported.

Regardless of the called method, you are limited by 10 API calls per day from a single IP address.

If you have already hit the limits or need access to other translation methods, consider the free tier or paid subscription plan.
