What are APIs?
In the scope of your career, APIs are one of the most important tools you’ll use. But what are they? The acronym stands for “Application Programming Interface.” In a nutshell, it’s a set of rules and code that allow two applications to communicate with each other.
If you think about our world today, technology is everywhere. And in order for all these different gadgets to communicate with each other, there has to be some sort of language that allows them to speak to each other. That’s where APIs come in.
An API provides developers with a way to access data and functionality from another application or service using code. To put it simply, APIs make it easy for applications or websites to communicate with one another.
How can you use APIs in your career?
The uses are endless! What do you need to know about your website users? What if your customers or clients would benefit from having more data on their customers?
For example, if you’re a developer who is trying to build a product that will help website owners determine their visitors’ locations, you can use an IP geolocation API like what we provide at MaxMind to perform these lookups.
Now that you understand what an API is and how it works, here are some APIs for you to try out.
ipXapi, an IP geolocation API
ipXapi is a free website monitoring application that also serves as a sophisticated geolocation and IP address identification tool. Because of its database and API, this service provides a high level of accuracy in IP statistics. It is linked to a number of well-known ISPs, who provide regular updates on new and current IP ranges. Because ipXapi is linked to several channels that provide real-time IP data, the API’s database is updated daily, with up to 24 database modifications per day.
The software supports both IPv4 and IPv6, and it gives IP data such as ping response time and location, device type and connection speed, hostname resolution, DNS control, IP network access details, SSL certificate information, WHOIS name server search, and many more features. You may browse its database at any time to get a full image of IP addresses, cities, and countries.
Klazify, a domain classification API
Klazify is the most effective solution for gathering client information and classifying websites. This technology supports you in running your business by getting data from a variety of sources. It uses an API to classify data and information acquired from a URL, email address, or domain.
Because it collects data automatically, this API is quite precise when it comes to data sorting. It extracts logos, information, market classifications, and domain security levels, among other things. Klazify employs over 385 subject categories. Facebook, Pinterest, and other well-known ad networks employ these categories.
Exchangr, a Forex rates API
Exchangr is a REST API that leverages the JSON data format to provide consumers and companies with accurate currency exchange rates and conversions. Exchangr FX API can handle even the most sophisticated business requirements.

Exchangr now accepts 164 currencies and eight cryptocurrencies from consumers worldwide. They obtain their information from a variety of commercial currency data sources and organizations. Before distributing it to clients, they blend it using an algorithm. It gives data that is updated on a regular basis at intervals ranging from 60 minutes to 60 seconds.
