Swiss Smart Travel

Swiss-smart-travel is a project developed in 36h during the StartHack hackaton in 2018. The idea behind this project was to solve the issue of multi-destination travel, mostly for people that travel to discover Switzerland. We created an API that takes as input a text query, a duration (1 day - 2 weeks) and start & end locations. As output, the API gives a list of the 10 most interesting cities regarding the text query, and a proposed tour in a subset of those cities.
