Bus departures at a given bus stop.Live bus data is not available for all stops. This operation will make useof different live data sources including NextBuses and TfL Countdown, tobring you a consistently formatted response with the best live dataavailable, or fallback to timetable. The results can be ordered by time orgrouped by bus route.The NextBuses datasource will be used for bus stops outside of London, andoutside of a few other areas where we have access to more direct live busdata. NextBuses is a more expensive source and the charge is adjusted to 10hits per request to reflect this. If you wish to avoid this hit charge anduse only the other data sources, add a nextbuses=no parameter.
