I would like to create a web application for my thesis in university. It's a simple app that has a few input fields, like "city", "start date", and "end date". With these information I would like to get the hotels in the given city with http rest calls to the API. I searched on google for good free APIs that I can work with, but found none. Do you have any suggestion?
My first (and usually last) stop when looking for an API is programmableweb.com
They list lots of hotel related APIs, but a quick search for "travelocity api" turned up theirs as well http://connect.lastminute.com/Developer . Other bookings sites may have their own available, but it was available via a quick search (duckduckgo vs. google but still....)
