I'm glad to announce a general purpose dictionary and thesaurus service that I'm developing exclusively for Geminispace, using WordNet. You can find it at:
This dictionary service uses WordNet, a large lexical database of English nouns, verbs, adjectives and adverbs from Princeton University. The thesaurus service pulls data from thesaurus.com. These sources were picked due to the open nature of their licenses, however, there are better options out there, which actually provide a RESTful API, albeit the license is a bit restrictive in my opinion. A good example is the Oxford Dictionary API.
For the last week or so I've been tweaking the output and asking some helpful beta testers to try it out and let me know what could be improved. If you are reading this and have found some bug or otherwise would like to suggest any changes or new features (or even letting me know of a good and free RESTful API, ideally with a Python wrapper), please send me an email to:
