What is Apility.io?
This is a collection of OSINT Threat Intelligence tools offered “as a Service” to help Product Managers, IT Departments, Enterprises and Start-ups know more about their potential visitors, users and customers.
What is a Hit?
A Hit is how Apility.io measures system usage. When you or your service request information from an API endpoint, one or more Hits will be consumed. Depending on the API endpoint type, it will consume a single Hit or several Hits. You can read more about the FAQ section of our Knowledge Base.
Can I use the API for free?
Yes, if you do not wish to register, you can try the API in anonymous mode. But we strongly recommend that you register and enjoy our Always Free Plan.
You can learn the differences between an Anonymous and a Free account here.
What is a Plan?
A Plan is a recurring subscription to our service. Depending on your Plan, you will have more or less Hits available daily, and more or less real-time alarms to use. You’ll also have more retention time for your data, and other management capabilities. Learn how our Plans and Pricing model works.
Do you store all the requests and responses?
Yes, we believe that an Analytics and Big Data tool helps to better understand user behavior. You can use our tools in the control panel, but we strongly recommend that you import your data into your favorite Big Data and/or Analytics solution.
How much data can you store?
Depending on your subscription plan, your account will allow a longer data retention period. From 1 day for the DEVELOPER plan to an unlimited retention period for the ENTERPRISE plan.

We incorporate a new domain blacklist: COINBLOCKER-DOMAINS. CoinBlocker is a collection of lists that can help prevent illegal cryptomining in the browser or other applications. Most cryptocurrencies are generated through the process known as “mining.” Much like traditional mining operations, these procedures require the use of energy and resources to complete a process which yields a financial reward. In the case of cryptocurrency mining, the energy required is electricity and computing power. Lurking behind the legitimate cryptocurrency mining community is another group of individuals and organizations that try to mine for crypto using illicit methods.Read more

The IPCATV4-DC is a list of IPv4 address that corresponds to datacenters, co-location centers, shared and virtual web hosting providers. In other words, IP addresses that end web consumers should not be using.Read more
