1. A service delivery method comprising: collecting, by a computer processor of a social application container computer system from an end user device via a header of said application and an application program interface (API) executing in the said social application container computer system invoked by an application running on the end user device, transaction data describing a transaction request of a user of said end user device, wherein said transaction data consists of an IP address of said end user device, a geo-location of said user, and credentials associated with said user; generating, by said computer processor based on said transaction data, transaction specific context, wherein said generating said transaction specific context comprises: invoking a preconfigured set of external provider services; and assimilating responses of said preconfigured set of external provider services into said transaction specific context; generating, by said computer processor based on user data present in said transaction data, user specific context, wherein said generating said user specific context comprises: invoking a preconfigured set of external social analytics provider services; assimilating responses of said preconfigured set of external social analytics provider services into said user specific context; and storing retrieved user specific context for future retrieval during an invocation process of said API by said user; and automatically and asynchronously combining said user specific context with said transaction specific context, wherein results of said automatically and asynchronously combining generates social context data associated with said invocation process; and automatically maintaining and developing, by said computer processor, logic based code for collecting and generating additional social context for every additional API executing in a social application container of a provider of said API, wherein said social application container comprises said social context; and generating, by said computer processor executing an application of said provider of said API, differentiated responses based on said social context, wherein said generating said differentiated responses is independent from said maintaining and developing said logic based code.
