I think http://bookinghunter should be in this list too.
What a great list,for Southern Hemisphere travel technology developers, Crusie Factroy is the largest cruise data API in use in Australia, New Zealand & South Africa (it works globally but we have just never taken it North of the equator). This 200 cruise lines, 4000 ports, hundreds of thousands of itineraries, flat file prices & a whole sale distribution system linked to 1000s of AU NZ & SA travel agents.
Dear Sir,
My name is Ayaan Khan and i am from Mumbai i would like to inform you that i have a tours and travels, recharges and utilities business over here. We are working here on distributor level we have more than 3000+ agents in all over India. We have most of 80% turn over in flights domestic as well as International. Now we are looking opportunity as an API or Master Distributorship. As i we have 3000+ agents and and also we have capability to create distributor or master distributor we need to expand our business as well as our turn over. So if you any concept as per my requirement kindly inform me with all the terms and condition as i am highly interested and want to start this kind of concept very soon.
Thanks And Regards
Ayaan Khan

Hi Wendell, Could you please add the Traxo API to your directory.
The Traxo API is a simple, REST-based API that contains structured travel data about Traxo member's confirmed past and future travel reservations. The documentation site (link below) includes request and response examples for all supported methods, required parameters, and supported formats and HTTP methods.
