What design pattern to implement in order to use a REST API?

I'm starting a new project that will require use an e开发者_StackOverflow社区xternal REST API that basically returns JSON and XML files. It's similar to the StackExchange API and I see every wrapper that has be done for that API has a different approach; for instance, stackoverflow-java-sdk uses the Adapter Pattern.

So, in order to make sure every new API feature will be included easyly... what would be the best design pattern?

The Bridge pattern can be used to encapsulate two interfaces so they can vary independently. Sounds like what you're interested in.
