API empowering developers: The API Market and Economy


The Application Programming Interface or API is a way for systems and programs to talk to each other. Different systems will have different ways to store and process data, and using an API with a publicly available instruction to retrieve this data will increase interoperability and capability of other systems that rely on this data or service.

As our business is providing a service via a paid API, I would like to take some time during this long holiday in Japan to look into and share some thoughts concerning the API market.

The History of APIs

APIs have been around for a very long time:

"The concept of an API pre-dates even the advent of personal computing, let alone the Web, by a very long time! The principal of a well documented set of publicly addressable "entry points" that allow an application to interact with another system has been an essential part of software development since the earliest days of utility data processing. However, the advent of distributed systems, and then the web itself, has seen the importance and utility of these same basic concepts increase dramatically." - Martin Bartlett 1

APIs are a source of innovation as it empowers developers with many different data and services that they can mix and match to produce much more effective and focused service to their own users.

With the prevalent of personal computing and the internet and with it the number of engineers that can harness this technology, it is now much more easier to share data or services via API which can be utilized using standard web protocols and development tools.

The Growth of APIs

Salesforce.com release of it's publicaly available API at the IDG Demo conference in 7th Feb 2000 kick started the web API market.

In "Tracking The Growth of the API Economy"2 Art Anthony shows us that public API grew from nearly an insignificant amount in 2006 to 15,000 in 2016.

Today ProgrammableWeb lists over 17k of available APIs.

Not only are there server side web APIs, there are also client side APIs like native plug-in browser extensions.

There are now as many APIs as types of data or services that you can imagine. Here are some examples:

Getting Social

del.icio.us which was founded in 2003 was a service for people to share bookmarks on the web. It is a good example on how you'd harness the standard way of calling for information on the web into a simple programmable interface to retrieve information.

Of course, we can't leave out Facebook. Facebook released it's Developers Platform in August 2006. It followed the same pattern of REst web APIs, with responses in XML following the common pattern of web APIs at that time.

Mapping

Google Maps lauched it's API in June 2006, partly due to pressure from rogue applications that was leveraging it's maps service to show information on the maps. The API allows developers to show Google Maps on their own websites, with specific data overlaid on the maps.

Entertainment

Netflix serves over 20 billion requests a month over it's API.3 Netflix's API serves all the devices that's hooked to it's platform consuming it's contents. From the engineering point of view, Netflix is a good study case to learn how they scale to cope with the increasing load and demands on their API.

Infrastructure-as-a-service Platforms

In 2007, Twilio launched as a API-as-a-product platform, which allows developers to make and receive phone calls. The API was launched in 20084 and in 2010 Twilio has added text messaging (SMS) to it's API.

Amazon's AWS is the behemoth infrastructure platform that we all know now. It consists of among others S3 (a storage platform) and EC2 (a computing platform) Even before it's web interface was avaialable to the public, it's functionalities can be accessed via an API. For S3, Amazon allowed developers to host files via an API and it charges developers for the amount of data they stored in the cloud per month. In 2006 this was a new billing model and with the S3, Amazon brought in what we now know as cloud coumputing.

With tens and thousands of APIs that will give you the service or data that you need for your application, developers are spoilt to the choice that they have to achieve their goals.

Monetizing models

Paid public APIs are common. Generally there are 4 big types of monetizing models which the API can help the business earn5:

Free

Free APIs are like Facebook's Developer's Platform API. You can access and use the APIs for free, which will add more contents on Facebook. Facebook then earns from the more ads that get's onto it's platform which is boosted by more users attracted to the increasing contents.

Developer Pays

This model is a straightforward model where the user of the API pays. Xoxzo's Cloud Telephony Platform API and Amazon's AWS APIs are examples. Paypal which takes a cut from the sales that you make when you use their APIs also fall into this model.

Developer gets paid

Google AdSense, Amazon Affiliates are examples of model which the developer gets paid, while the business also earns from a different source, like the business trying to sell merchandise on Amazon, or the owner of the ads in the case of AdSense. These are usually revenue share setups.

Expedia, which says that 90% of what they do is through their APIs, has around USD2 billion per year of business going through it's Affiliate Network.

Indirect

3rd party applications built on the eBay open platform, and also 3rd party Twitter clients are examples of the indirect model. These two are examples of ways for the business to aquire contents, which leads to a better user exeprience in their main businesses.

The New York Times utilizes APIs for contents syndication, which will pull visitors to it's main site so that they can earn on ads revenue of subsciption fees for their contents.

I think there is a fine line between the indirect and the free model, because both are basically "free" to the user. I guess it will depend on the underlying monetizing model that you have for your business. In these cases, usually you would consider the API as an additional funnel that leads to your main business.

While in Japan...

In Japan, ITR states that the amount of revenue for the API market for 2015 was 80% more than 2014, and it predicts the between the year 2015 to 2020, the average growth for the API economy is 41%, with revenue gained in 2020 a whopping 5.6 times compared to 2015.6

ITR points to the reason of the increase was due to the implementation push by big companies. But at least for the Japan market, it seems that these are not public APIs but APIs which are only opened to partners.

Terrie Lloyd, a long time Japan resident of Japan and comments on the tech industry has a different view. He believes unlike the rest of the world where APIs are used extensively, due to the controlling nature of Japanese businesses over business relationships and company internal data, not to mention the technical challenges for smaller companies, the opening up of APIs to the public is not as fast as the rest of the world.7

I believe it will be a matter of time that business in Japan will also be providing public APIs readliy accessible to developers. Business models might be different than for example Twilio which charges the developers directly per usage, but might be more of indirect or partnership agreements where the businesses themselves will have a stronger control on the relationship.

In Summary

The API economy and market will continue to grow, due to the pull factors such as ease of computing resources (cloud computing), increase of mobile devices which requires more and more real-time data and the growing number of engineers which can handle and work with web technologies. The push for more efficiency and need for faster time to market also contributes the growth of the API.

New industries such as big data processing and AI require data to function, and these data will more and more be made avaialable via public APIs.

The business models for APIs are pretty straightforward, and can be the main revenue generator (like Xoxzo or Expedia) or an indirect channel to acquire contents (like eBay). Either way, there still needs to have a specific and comprehensive strategy for the business part of the API itself. It is not something that you do as a "side" service.

But APIs are never done. They grow and need to be refined based on actual data used, who is using it and it's use cases.8
