Here you can find some code examples showing how easy integrating the Oraclize Ethereum API is.
Thanks to our Ethereum API helpers using Oraclize in your Solidity/Serpent code is very easy.
In Solidity it is as simple as inheriting the usingOraclize contract: this will provide you some functions, like oraclize_query, which make it trivial to leverage our technology straight away.
If you are using Serpent just import oraclizeAPI.se and enjoy the same Oraclize helper functions via macros!
