The Oxford Dictionaries API has a number of flexible plans to suit all types of application. Registration is free and you can get started using the data straight away with your unique App ID and App Key. If you want to try out the API before registering, the live documentation offers a playground to try real calls and view the data, but you will need to register in order to experience the full features and capability of the API.
The Oxford Dictionaries API offers an easy way to access powerful lexical data (words, definitions, translations, audio pronunciations, synonyms, antonyms, parts of speech etc.) to use in your apps and websites. Our mission is to extend learning and education worldwide, so there are very few usage restrictions for the API and our data, but please read our Terms & Conditions before signing up. If you are unsure about anything just let us know and we'll be happy to discuss a solution for you.
As well as having dictionaries in the some of the biggest languages, we are committed to building content in 100 of the world's digitally under-represented languages as part of our Oxford Global Languages initiative. In the API, we so far have content in English, Spanish, Romanian, isiZulu, Northern Sotho, Latvian, 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.
