So, if I have just completed designing a problem-solving API, what should be my next move? For example, how can I earn using that API? Or How should I market my API?

What Is An API Marketplace?

There are several online marketplaces these days such as Amazon, Facebook, etc. Now, if I need to sell an item on these marketplaces, I will simply list my item on these websites. These marketplaces will automatically send the related customers to my products. This is how an API marketplace works too.

As a provider of API, I will list my API that developers or business owners can use by purchasing it. However, there is one more thing that I would like to add here. A typical API marketplace may have two components such as API provider portals and developer portals.

The developer portal helps developers to find different subscription plans to integrate APIs in different projects. On the other hand, the provider portal helps providers to publish APIs for developers. This is whats an api marketplace can do to interact with providers and developers.

What Is The Difference Between API Marketplace and API Portal?

API portals are either custom developed or they are created through a template for the management of API products. It is common that only one API provider deploys API portals that allow to understand, integration, and deploy APIs for developers. An API portal gives access to documentation including features, tutorials, and specifications.

Let me tell you one thing clearly, API marketplaces have replaced API portals in this era of technology. People still use API portals but there is more demand for API marketplaces. They help you sell API and earn through it.

API marketplaces have unlimited plans, APIs, and benefits. This is because the API marketplaces give the opportunity to several API providers to showcase their products.

If I were a developer, I would always like to choose an API marketplace over an API portal. Because I know that my APIs would get higher exposure and more target audience on the API marketplace.
