A computer-implemented method for retrieving information from information services and providing it to a public application programming interface (API) includes receiving a first request data message using a core discovery agent, the request data message including at least one requested datum, for which a value is sought, and at least one known datum, for which a value is known; calling a resource locator to request a location of an information service that provides a value for the requested datum; calling a resource façade to contact the information service; transmitting a first information service message including the requested datum and known datum from the resource façade to the information service; receiving a second information service message from the information service including a value for the requested datum; and transmitting a resolved data message including the requested datum and its value from the core discovery agent to the public API.
