Hello,
I have more than 10 years experience in hospitality domain web application. I had implemented more than 200 OTA API as like (Expedia, bookings, Airbnb, Makemytrip etc...).
I developed automated system for fetch reservation details from OTA website and update availability of room.
Could you please let us know which one API do you want to scrape. I will have to check the API doc for final price quotation.
Some API are easy to connect by simple curl request, I had experience of many technichal API, who needs special requirements into header for connection and send response xml.
Thanks
