What can I do with the Oxford Dictionaries API?

The Oxford Dictionaries API offers an easy way to access powerful lexical data (words, definitions, translations, audio pronunciations, synonyms, antonyms, parts of speech, and more) to use in your apps and websites. Please read our Terms and Conditions before signing up. If you would like to discuss your use of the API then please complete the Enterprise form to contact us.

Which dictionary does the API data come from?

The Oxford Dictionaries API provides access to our current English dictionaries. This is our most comprehensive current English dictionary dataset and includes enhanced, updated versions of the Oxford Dictionary of English and the New Oxford American Dictionary. It includes more than 350,000 entries and is regularly updated with new words, senses, and definitions.

We also have content in Spanish, German, Portuguese, Romanian, Malay, Indonesian... and many more, and we're adding more all the time. Take a look at our supported languages page for the most up-to-date list.

Is this an Oxford English Dictionary API?

No! Oxford Dictionaries and the Oxford English Dictionary both come from the same publisher, Oxford University Press, but are different products. While Oxford Dictionaries reflects current usage of English, the OED records how language has developed over time. If you are interested in accessing the OED data through an API, you can find more information here.
