An API marketplace is more than an API developer portal where potential consumers discover and subscribe to APIs. It provides the means for a diverse group of people to design and publish APIs, along with tools, documentation, and incentives to participate, such as monetization and evangelism.
StackMob, a leading cloud-based, mobile Platform as a Service (PaaS) provider, has just announced the launch of the StackMob Marketplace, a developer-ready API modules online store. In addition, StackMob is now offering a new pricing model that offers free StackMob API calls to developers.
Online marketplaces are the new normal. Multiple sellers can offer their goods in one centrally located place, and buyers can find desired products from multiple vendors and purchase them with one click. Developers on the hunt for marketplace APIs should check out this list of popular ones.
