Abstract

An API optimizer generates an API (application program interface) customized to a particular process. The resulting optimized API includes API services that minimize network access. The API optimizer applies heuristic rules from a rules database to generate, on the basis of the application logic flow for that application and the set of objects, those services that minimize network access.
