The Umo IQ Public Feed (formerly the NextBus Public XML Feed, revision 1.24, 18 May 2021) is Cubic Transportation Systems' anonymous, unauthenticated real-time transit feed. A single GET endpoint in XML (/publicXMLFeed) or JSON (/publicJSONFeed) form is driven by a command query parameter: agencyList, routeList, routeConfig, predictions, predictionsForMultiStops, schedule, messages, vehicleLocations and vehicleLocation. It is licensed free of charge to Umo IQ customer agencies and carries published per-IP data limits (2 MB per 20 seconds) and a 10-second polling floor.
