# Omio Trip Search API Documentation

Omio Trip Search API Documentation Search trips by train, bus and flight between two places on a date, one way or round trip. Each trip has the carrier with logo and codes, the price in minor units (cents) with its currency, duration in minutes, the number of stops, departure and arrival times and places, every leg with line number, class and zones, the changes between legs, the fare offers, tickets left and flags for split tickets and routed connections. The response also carries the number of trips per mode, the lowest price per mode and the search id for the trip and providers endpoints. Trips are sorted and paged by Scrappa over the full result set: price and duration sorting is done by Scrappa (sort_source is client), departure, arrival and smart use the Omio order (sort_source is server). Page 2 is always the next slice, never page 1 again. Add return_date for a round trip. The results are then the outbound trips (trip_type is round_trip), and the price of each is the lowest total price of outbound and return together. Omio gives the return trips only for one chosen outbound: open it with the trip endpoint (search_id and trip_id) to get its return_options. Search results are live and a search takes a few seconds. Omio is not affiliated with Scrappa.
