You will be charged for the month in advance and billed for any additional calls at the end of the month. You can change your plan at any time in your developer account.


The Wordlists endpoint allows you to extract large lists of words from our dictionaries by taking advantage of the rich tagging across domains, registers, lexical categories, and regions. Each Wordlist request can retrieve up to 5,000 words, and therefore we weight Wordlist requests differently from other requests to the API. One Wordlist response is equivalent to 500 individual requests.

Full and filtered wordlists are also available to license or purchase. To discuss your requirements please Contact us.
