Embodiments of enhancing API servicing schemes are disclosed. A set of proxy code associated with servicing the API requests of an application is analyzed during development time to determine if any portion can be modified to improve the service scheme, prior to executing the set of proxy code in a runtime. After the set of proxy code is deployed in a runtime environment, performance data associated with the current service scheme is collected and periodically used to determine whether the service scheme for the API requests of the application is to be updated.
