The Macmillan Dictionary API offers access to an extensive range of data developed for the renowned Macmillan English Dictionary, including:
All of the above is available in both a British English version and an American English version.
So if you're developing word games, educational apps, language-learning websites, or other English-related digital applications, the Macmillan Dictionary API will provide precisely the sort of content you're looking for – customizable in the manner you choose.
For use within non-commercial products, we offer access to this authoritative content for free, enabling you to enhance your product, and add value to your pages.
For commercial use – or for usage beyond a 10,000-call monthly limit – please contact us by clicking here, and we'll agree terms and conditions on a case by case basis.
We'll then send you an API Key by email, and details of our API Sandbox where you'll be able to experiment with the data for an agreed time period.
We look forward to future collaboration, and to the launch of your new, innovative digital product, powered by Macmillan Dictionary data.
