Where to apply for licences on large and multilingual dictionaries?How to choose the right one?

Good day, there was a task in the mobile application to translate text a user in the chat since the app is paid - please tell me if anyone faced or knows where to find such dictionaries that can be embedded in a mobile application correspondence(android and iphone), approximately how much is the license, are there any pitfalls when dealing with licensees, and how to select based on what will be implemented directly.
Thanks in advance.
Sincerely yours, Victor.
