Python example

import requests
from google.transit import gtfs_realtime_pb2

# Legacy feed, no longer updated since 2026-09-21: query a timestamp before that date.
# For current data use tec/gtfs-rt-trip-update.
params = {
    "timestamp": "2026-09-15T12:00:00+00:00",   # ISO accepted; epoch also works
}

url = "https://api.mobilitytwin.brussels/tec/gtfs-realtime"

data = requests.get(url, headers={
        'Authorization': 'Bearer [MY_API_KEY]'
}, params=params).content

feed = gtfs_realtime_pb2.FeedMessage()
feed.ParseFromString(data)

# The feed carries trip updates only: list cancelled trips and delays > 5 minutes
for entity in feed.entity:
    tu = entity.trip_update
    if tu.trip.schedule_relationship == gtfs_realtime_pb2.TripDescriptor.CANCELED:
        print(f"Trip {tu.trip.trip_id} on route {tu.trip.route_id} cancelled")
        continue
    for stu in tu.stop_time_update:

        if delay > 300:
            print(f"Trip {tu.trip.trip_id} — {delay // 60}min late at stop {stu.stop_id}")
