Understanding APIs and Web-Based APIs – Web-Based Application programming interfaces

General Meaning Of An API

In general meaning, an API, or Application Programming Interface, is a computer science-related term that refers to a way for two applications to talk to each other.

One important information to keep in mind is that when people talk about API, there is a 95% chance that they mean web-based APIs.

Web-Based APIs:

Web-based APIs are the gateway to access a company’s data or services. Whether it is Google, Facebook or Lunarcrush. If that company has data or services and want to provide them, it will do that through one or multiple APIs.

For instance, Google is an empire built around the use of APIs. It has over 92 APIs available, such as Google Maps, Analytics, Calendar, and Contacts.

Another example would be Facebook. The company has an API that allows the user to retrieve Posts, User and Groups from their Data Centers. Meaning that APIs provide an entire infrastructure for anyone to take advantages of, and at a fair price. Otherwise, you need to build the entire infrastructure yourself to collect such information.

From adapting it as a partial income stream, to an entire business model, companies are using it in all sorts of ways. That’s why it is said that 55% of companies are using web-based APIs as revenue stream.

An example that is interesting to note here is that the cloud API market alone, which is just a small part of the whole API market, is estimate to be worth 1.7 billon dollars by 2026 according to alliedmarketresearch.

Two other good examples would be Salesforce.com shelling out $6.5 billion for MuleSoft, the management system for APIs, and Visa who agreed to pay $5.3 billion for Plaid (Forbes.com).

In simpler term, companies provide APIs as an industry standard way to solve problems and make revenue on their investment.

Business - API

By analyzing a recent SlashData survey. And according to nordicapis, we find that 89% of developers use APIs and just 10% of them don’t use them. The 89% that use the are divided in two, 69% use third party APIs, 20 use private internal APIs.

Other studies have shown that there are 19.1 Million API Developers in the World, which pushes us to ask, why does one need or want to use the API?

The answer to that differs! Each one using an API has his own needs for that. One may use it just to collect some data for an analysis study that he is working on. Another would use it to build a fully-fledged business upon the data he gets.

Maybe you sell items, and you would use a web-based API to get the products that were sold the most on a website in order to start selling them yourself.

One famous case nowadays would be for investors. If you are an investor in stocks or cryptocurrency coins, and you need live data of a specific stock or coin to apply a specific algorithm on that data to help you make better decisions, an API is what you will use.

Other uses of APIs are meant to automate certain tasks or workflows through the use of Bots that advantage of APIs to automate Posting, liking and commenting on Social Media..etc.

Examples of that would be the Messenger Chat Bots that replay to clients’ messages automatically. Or Telegram Bots that post specific messages in specific channels or groups when an event occurs.

To simplify it, if you have a problem, as a developer, business owner or investor, there is probably an API that can solve that for you.

Important information to have about a Web-Based API Before start using it

To use a specific API, you usually need to understand the following steps:

Does that Company/Business have an API?

The first step is to always check if a specific company has an API. If the company has it, check it out, else search for another company that does the same thing and that may have it. For example you want data about the Tesla Stock, Some Companies have APIs that will provide you wit live data, and others don’t.

Is it a free API or a Paid API? – The companies business model

Companies provide APIs at different price points, and wrapped with different limitations.

For example, the Twitter API is free of use and allows you to tweet, like, comment get and save data.

On the other hand, Lunarcrush API is a paid one, the price and limits will be applied to each user differently built upon an agreement with the company once he contact them.

What data does that API provide?

One import information to have is what data does the company provide through their API. One should always check out if the provided data is helpful to his use case or not. Let’s say you want to get live stock data, but the company provides data with 2 minutes delay. that would be beneficial to you if you are using it for an analysis study, but not if you are a day trader.

That’s why it is very important to understand what exact data you will get.

What are the limits of that API?

Limitations are put together by each API provider to prevent the excessive use of their resources like servers, which usually, translates to money that they will have to pay. Paid Web-based APIs usually come up with different plans for different use cases. The less the limitations, the more you usually pay.

example: When using the Twitter API, one can only post 300 Tweets or Retweets during a 3 hour period.

How to use an API? – The Technical Part

Using an API is purely technical. The developer using it usually needs to have a basic understanding of the HTTP protocol, requests, and responses. The whole process is referred to as API calls.

In simple terms, we send requests to the API using the HTTP protocol, and then get back a response that hold that data we want.

A good information to have is that most API calls nowadays are made using Python and the Requests library.

Some APIs are easy to use, and others are highly technical, requiring prior knowledge to understand how to implement them. Complex APIs have a ton to offer but unfortunately, they’re not available to the masses.
