API Aggregators

API Aggregators Reviews and Ratings

What are API Aggregators?

API aggregators simplify application development by providing a single API in front of multiple different services from different providers, each of which may have its own set of APIs. Industry-specific API aggregators accelerate time to market in many industries such as banking and healthcare. API aggregators reduce the time to market when building applications, because it is faster to use a single API than to integrate directly with many systems using different APIs. They provide a route to market for application providers' offerings. For an application provider without APIs, the API aggregator fills this need by providing prebuilt APIs. This can be an inexpensive way to provide customers or partners with APIs. However, API aggregators bring a layer of disintermediation. Unlike API management, which focuses on governing and securing an organization’s own APIs throughout their lifecycle, API aggregators primarily provide unified access to external APIs. They are increasingly common in industries with some commoditization, such as banking, insurance and SMS messaging and are used by developers and startups who need quick integrations, enterprises and SaaS providers managing multiple APIs.
