Frequently asked questions

How can I trial the API?

In order to trial the OD API, you will need to sign-up here for the Sandbox. Upon signup you can navigate to the developer portal to view your unique App ID and App Key which will allow you to evaluate the API via the documentation or your own code or test tool (e.g. Pyton code, Postman, CURL etc.).

What’s included in the trial?

Access to the Sandbox includes a finite amount of 500 calls to all languages and endpoints for the dictionary datasets, and is limited to the first letter of the alphabet. See more info here.

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.

Can I use the API in a commercial project?

Use of the Oxford Dictionaries API as a commercial product is permitted in line with our terms and conditions.

Can I use the Oxford branding in my application?

Please visit our branding resources page for the guidelines on using our branding and the appropriate logo.

Can I cache data?

Caching or any saving and use of the data offline is only permitted under an Enterprise license. Please, complete our Enterprise form to request this functionality. Including estimates of how much data you would initially anticipate caching will expedite the consideration process.

Where can I find your terms and conditions?

Our terms and conditions can be found here.

Which languages do you support?

In the API, we currently offer content in English, Spanish, German, Portuguese, Romanian, 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.
If you’re looking for a dictionary dataset for a language which isn’t currently available via the API, we might still be able to help. We have over 35 language datasets, from Afrikaans to Vietnamese, available to license via Oxford Dictionaries Licensing.

I can't see the language I need. Will you include it in the API?

Please take a look at our supported languages page. If your requested language isn't available through our API, it may still be available to licence. Please do get in contact to let us know your requirements here.

What does this error code mean?

If you explore our documentation page, you will find information on what each error code might mean under the 'response messages' for each endpoint.

Please contact us if you have any questions or comment about the API.
