What Is an API Marketplace?

An API marketplace is a marketplace that combines API suppliers and customers on a single platform. A marketplace for APIs has a number of different parts, including a provider portal and a developer portal.

On this platform, API sellers (developers or companies) can advertise their APIs for sale, and API buyers (other developers) can view and purchase them.

An API provider can sell their APIs on an API marketplace and make money off of them by providing different subscription options. API marketplaces also assist developers and potential customers in locating APIs by providing useful search tools, collections, and categories.
