Transportation — entry 048 of 69
Transport for Los Angeles, US
LA Metro's real-time feeds now run on the Swiftly platform rather than an in-house system, so developers must request a free API key through Swiftly's sign-up form before they can pull GTFS-realtime vehicle positions (5-second refresh) and trip updates (10-second refresh). A newer beta endpoint separately exposes scheduled bus-cancellation data, though Metro's own docs flag that its schema is still subject to change.
