Send an email if you couldn't find an answer to your question here.

What is Apility.io?

It is a collection of Threat Intelligence tools delivered “as a Service” to help Product Managers, IT shops, Enterprises and Start-ups to know more details about their potential visitors, users and customers.

What is a Hit?

A hit is how Apility.io measures the use of the system. When you or your service request information to an API endpoint, a number of hits will be consumed. Depending on the type of the API endpoint it will consume one or several hits. You can read more the FAQ section of our Knowledge Base.

Can I use the API service for free?

Yes! If you don’t want to register you can test the API with an Anonymous account. But we strongly recommend to register and enjoy our Free Forever Plan. You can learn the differences between an Anonymous and a Free account here.

What is a Plan?

A Plan is a recurrent subscription to our service. Depending on your Plan, you will have more or less Hits available daily. You will also have more retention period for your data. Learn how our Plans and Pricing model works.

Do you store all the requests and responses?

Yes. Analytics and Big Data helps you to understand better your users. You can use our tools in the dashboard, but we strongly recommend to import your data into your favourite Big Data and/or Analytics solution. 

How much data can you store?

Depending on your subscription Plan your account will allow a larger data retention period. Starting from 1 day for DEVELOPER plan to unlimited retention period for ENTERPRISE plan.
