A computing device (308) includes communications circuitry to communicate with a first access network (306) and processing circuitry. The processing circuitry is to perform operations to transmit an authorization request for a vehicle-to-everything (V2X) communication to a V2X application function (312) within a service coordinating entity, the request transmitted from the device via the first access network. V2X configuration parameters are received from the service coordinating entity, via the first access network. The V2X configuration parameters are received in response to the authorization request and based on V2X subscription information received by the V2X application function via a V2X application programming interface (API) within the service coordinating entity. A V2X communication link (340) for the V2X communication is established with a second device (326) based on the V2X configuration parameters, the second device associated with a second access network.
