UPDATE - SORRY GUYS DUE TO A REMOVAL REQUEST FROM ALIBABA GROUP, I AM NOT ABLE TO COUNTINUE THIS PROJECT !
World's 1st Aliexpress API
Allows You To Fetch the product details, so its very different form affiliate api as the fetched data is simply outputted for the selected URL. Just Post The url to the xgo.php and it will fetch you all the details about that product and will return it in more simple and elegant response. API is powered by heroku for now and the server location is in europe which will provide you very good results.
HOW to use ? just post get request to index.php -> index.php?url=producturl
