You can update your billing details from your API dashboard.
Email us at apiteam@wordnik.com with your Wordnik username, and we'll check it out. Remember that we reserve the right to turn off keys that are exceeding our limits, that don't obey our attribution requirements, that have been accidentally or deliberately made public, or that show other signs of abuse, at our sole discretion.
Absolutely. We want your product or service to be successful! We do ask that if you have a commercial app (beyond the proof-of-concept stage) that you upgrade to a paid API plan, so that we can continue to provide our API service.
Do keep in mind that your app cannot be a duplicate of the Wordnik API itself!
Here are some examples of acceptable paid or free apps and sites:
If you aren't sure whether or not your app qualifies, ask yourself: "Is my app or service a clone of the Wordnik API?" If not, you're probably good. Still not sure? Please email us at apiteam@wordnik.com.
Users with a paid API plan can temporarily cache display text (not the raw data sent from our API) for offline use. We do not allow caching of any data with the Basic Plan.
We also offer a downloadable dataset of nearly 200,000 words and definitions optimized for use in word games. You can find more information about that dataset here.
Absolutely. Please send screenshots to apiteam@wordnik.com. Unfortunately, we are unable to install applications.
Unfortunately we are not able to amend our terms of service for users on the Basic, Hobby, or Pro plans. Depending on the adjustment, some separate agreements may be possible for users with Enterprise plans. If you have significantly different requirements, please email us at apiteam@wordnik.com!
We're happy to chat with you about raising your limits! Please email us at apiteam@wordnik.com and include a link to your app (or at least a description) and any other information you think we might need.
Please note that we do not automatically raise limits for personal or private apps.
Now that Wordnik is a non-profit we have to support our mission—to find and share data about every single word of English!—by charging for our API services.
We spend thousands of dollars every month to provide our API and web services, and donations and grants offset very little of our expenses.
In addition, changes to our data licensing agreements mean that we can no longer offer some datasets completely free of charge to API users.
We're glad you asked!
If you find the Wordnik API useful and want to support our work, we encourage you to subscribe to a paid API plan.
You can also support Wordnik by donating directly, adopting a word or buying a Wordnik t-shirt!
