Looking through our directory of travel APIs and getting lost? That's no surprise; we've cataloged 168 of them so far. Fortunately, Valentin Dombrovsky, CEO of Travelatus did a great service by focusing on the 5 he says, "are the ones that offer interesting opportunities for your site—no matter who you are, an OTA, an airline or a hotel chain, for example." Writing for Tnooz, the magazine that talks travel tech, his 5 picks are rome2rio, DealAngel, Evature, Flightstats, and InKnowledge's Taxi Fare Calculator.
