I think there is no API provided by flipkart.
But
Flipkurl[
^] is a php - curl based library to access the contents of flipkart.com site, login into it, search book listings, add books to cart, move books from to wishlist, read contents of cart, etc.
You can email a contact at flipkart and ask if they expose any APIs that you can use (they may charge for this, not sure).
As there are sites like
http://www.indiabookstore.net/[
^] and
http://www.mysmartprice.com/[
^], so they must be doing something to get the data from different websites.
Alternate method
If they don't expose APIs then you can go for
asp.net screen scraping[
^].
Some good articles for asp.net screen scraping are as follows.
1.
Screen Scraping with C# for ASP.NET[
^].
2.
C# Scraping HTML Links[
^].
3.
.NET Screen Scraping in depth[

4.

Good luck. :)
