It's really easy to use RapidAPI to start consuming APIs in your app. Using RapidAPI, you can consume any API using a unified, REST format that is easy to understand and embed in your app. Moreover, you can view all of the APIs you are connected to using the dashboard, which monitors things like the number of API requests, latency, and error rates. For more on using APIs, check out our Basics - Your First API Call section or our RapidAPI for Developers page.
