Tour operators can't find travelers who will hire them, while travelers are leery of tour operators because they don't know who to trust. And those who bundle and sell tours are caught in the middle. World Travel and Tours solves that hairball by maintaining an inventory of reputable guides, and providing an intuitive platform that tours, tour affiliates and travelers can use. Key to this is the World Travel and Tours API, which accepts HTTP GET calls and returns data in XML. World Travel and Tours joins some 272 travel APIs in our directory.
