Abstract: Aspects of the subject disclosure may include, for example, a method that includes determining, by a processing system, whether a transmission from a client device includes a request to participate in a sponsored data session. If a sponsored data session is requested, the request is sent to equipment of a sponsoring entity. The processing system receives a list of data items available from the equipment of the sponsoring entity in the sponsored data session; initiates the sponsored data session; and generates a session identifier for transmission to the client device. The processing system also determines whether a subsequent request received from the client device corresponds to a listed data item, and causes a sponsored data rate to be applied to a client account for transfer of the data item. Other embodiments are disclosed.
