Best API Marketplaces to Sell Your APIs

An API Marketplace is a public hub where API providers publish APIs for both developers and partners. 

The Marketplace is equipped with components such as developer and provider portal.  Using the platform, the API providers can list the APIs where the buyers can see them and then make API purchases.

In layman’s terms, one can compare an API Marketplace to an e-commerce website such as Amazon. When you want to sell an e-book (similar to an API), you can list it on the site where the viewers can see and purchase it if you like.

Similarly, an API Marketplace enables a provider to list their APIs for sale and also monetize them with the help of different subscription plans. This part is known as the provider portal. The marketplace usually takes care of payment structure, managing the users, code snippets, documenting, and testing the market without investing straight away in an API gateway.

The API Marketplace also is helpful for the developers as the purchasers can find the APIs with collections, categories, and so on. This is known as the developer portal. One can compare the APIs, and see the prices and other essential details before purchasing an API suiting their needs.

What is the difference between API Marketplace and an API Portal?

API portals use customizations or templates for API management products. These are provided by an API provider which permits the developers to understand and help integrate them.

However, API Marketplaces became more popular. An API marketplace differs from portals where they integrate APO providers into a single view and add-on search functions for developers to browse through an array of APIs. 

One of the attractions of using a marketplace is simplicity. Developers can visit the marketplace to cater to a majority of their needs as an API consumer. 

This approach is beneficial for API providers as being part of the marketplace, for some providers, deploying it to a marketplace can result in dispensation of the portal altogether.
