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!
It is highly recommended to avoid using serpent, especially in production. The examples have been left for historical reasons but support for it is no longer maintained as serpent is considered outdated and audits have shown it to be flawed.
