Usage

maison is the search word
translations=true includes translations in the response

Pros

Free to use
Simple request structure
No API key is required
Supports many languages

Cons

Limited to 1000 requests per hour per IP address
More focused on dictionary lookups than full sentence translations

Licence

The API uses Wiktionary data under the CC BY-SA 4.0 license. Attribution to Wiktionary and FreeDictionaryApi is required when using the API.

Conclusion

FreeDictionaryApi could work well for simple dictionary or word translation features. It's free, easy to use and does not require authentication.

Conclusion

LibreTranslate could be a good option for full sentence and multi language translation support. It allows self hosting and gives more translation functionality than dictionary APIs.

Do we want this?

Translation functionality could be a fun addition to the project for translating simple words between multiple languages. Based on the research, FreeDictionaryApi seems to be the most suitable option if the goal is mainly simple word translations or dictionary style lookups. It's free, simple to use and does not require authentication. LibreTranslate supports more translation options like full sentence translations and can also be self hosted. However, it may be unnecessary if the feature is only intended for translating individual words. Both APIs support multiple languages and legal to use as long as their license requirements are followed.

Looks good, we will create an issue for implementation of a view using FreeDictionaryApi.
And the conclusion will be added to the wiki.
