Frequently Asked Questions

What are Pay-As-You-Go plans?

Our plans do not include any setup or cancellation fees and no minimum charges. We track the number of API calls you make and bill you exactly for what you've used.

When will I be billed?

We bill you monthly and automatically charge the credit card that is on file with us.

Which API calls do you charge?

We only charge you for calls made to the Entity Linking Service. All calls to the Knowledge Graph Service are free, no strings attached.

Can I use the API for free?

You can continue to use our API for free as long as you wish. Just stay on the Free Plan. Your quota on that plan is 1,000 API calls/mo.

Can I register for a paid plan without a credit card?

Please contact us so that we can discuss further details on your planned API usage.

Is my data secure?

Sure! Please have a look at our privacy policy and terms of use, which explains how we handle your data.

What happens when I exceed the monthly quota?

You will not be able to send any further requests until the beginning of next month. At any time, you can upgrade to a paid plan from your account settings, which removes the quota.
