  Transit is a Montreal-based mobility app that provides real-time public
  transit, multimodal trip planning, and shared-mobility navigation across
  1,000+ cities worldwide. The consumer app displays nearby buses, subways,
  trains, bikeshare, scooters, carshare, and on-demand transit the moment it
  opens, and is augmented by "GO" crowdsourced vehicle locations contributed
  by millions of riders. Transit operates a partner program for transit
  agencies, mobility operators, and third-party developers, exposing its
  routing, real-time, alerts, and shared-mobility surface through the public
  Transit API (api-doc.transitapp.com, v4 stable). The v4 API is a single
  OpenAPI 3.1 contract covering nearby routes and stops, stop departures,
  multimodal trip planning, placemarks for shared-mobility vehicles and docks,
  available networks, route and trip details, service alerts, and real-time
  vehicle positions. Authentication is an apiKey header; the free tier allows
  5 requests per minute and 1,500 calls per month after key approval, with
  custom commercial plans available through partners@transit.app.
