Pricing questions

What counts as a call?

Every request to the API counts as one call, including a batch request of up to 500 words. Errors caused by a bad key or a missing word are not charged.

What happens if I go over my monthly calls?

On the Free plan, calls stop until the 1st of the next month. On paid plans your app keeps working and extra calls are added to your next invoice at your plan’s overage rate.

Can I change or cancel my plan?

Yes, at any time from Account → API. Cancelling keeps your paid plan until the end of the period you have paid for, then moves you to Free.

Do you offer yearly billing?

Yes. Yearly plans cost ten times the monthly price, so you get two months free.

Which currency do you charge in?

All prices are in US dollars.
