A public cloud can host a multi-network service for transceiving common requests and responses for multiple networks. The public cloud can receive requests from the networks to join the service via an application programming interface (API). The public cloud can receive a request from a client device for information from one of the networks via the service, and the public cloud can transmit the request to that network and corresponding request(s) to one or more other networks joined to the service. The public cloud provider can receive multiple responses to the request and corresponding request(s), and transmit the responses to the client device.
