Working in partnership – APIs and licensing

Create your own solutions using our global language data.

Innovate with our data

From simple spell-checkers and language learning to augmented reality and artificial intelligence, our data is used by the world’s most innovative companies.

Google, Amazon, and other major tech companies use our data to power their products and services. That data is now available to everyone through our API programme, the Oxford Dictionaries API, which developers use to create new online technologies and innovative apps.


We provide comprehensive and up-to-date multilingual language content from Oxford University Press (OUP) and trusted partners in the form of distinguished dictionary brands worldwide. All content from our partners is authenticated by OUP and conforms to standard data models.

We offer monolingual, bilingual, synonyms, and children’s datasets for a wide range of languages to help you develop applications and digital services for people around the world.

Developer API portal

Our dedicated API self-service portal offers instant access to our world-renowned dictionary content including words, definitions, pronunciations and translations for a wide range of languages. The data is semantically linked for maximum flexibility.

If you want to license larger datasets or do not want to use an API, contact us and we can arrange flexible plans and data customization to suit your needs. Talk to us about your language requirements – in some cases we can allow you to ‘try before you buy’ and see if our data works for you. As well as providing access to Oxford Dictionaries data via the API Developer Portal, we also have flexible plans and data customization options for larger partners.

Our data is open. Anyone can access it, evaluate it, and use it – often free of charge
