Here are different versions of Interlayer for Polyglot (https://github.com/Allnorm/Polyglot)
- For Google API - Python Client for Google Cloud Translation https://github.com/googleapis/python-translate, Apache-2.0 License
- For Google Free API - Py-googletrans https://github.com/ssut/py-googletrans, MIT License
- For Yandex API - not required
- For using Google Free API you should select version 4.0.0rc1 and don't update its dependencies after installation. The use of this version is strongly discouraged, it is unstable and does not translate correctly.
- The Yandex API interlayer updates the token every hour, which can lead to bot freezes for a period of about five seconds during use.
