Is there an API from Apple where i can achieve the above.

Isn't this what the "App store" app is doing by default? I am not sure Apple is going to approve that if you manage to do something like that. Apple certainly wont want a duplicate....

You simply cannot. Apple forbids you from scraping their sites in Apps on the App Store.

From Apple's "Review Guidelines" - section 12

• Scraping and aggregation
  • Applications that scrape any information from Apple sites (for example from apple.com, iTunes Store, App Store, iTunes Connect, Apple Developer Programs, etc) or create rankings using content from Apple sites and services will be rejected
  • Applications may use approved Apple RSS feeds such as the iTunes Store RSS feed
  • Apps that are simply web clippings, content aggregators, or a collection of links, may be rejected
