Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time. There might be situation where smart contracts would need to consume third-party api, In such cases Oraclize might be handy. Oraclize is an interface that provides mechanism to communicate via thirdparty api and smart contracts.

Caution! Please note that in order for the future timestamp to be accepted by Oraclize it must be within 60 days from the current time. Private chain scenarios. If you are currently using private chain, you need to use the Ethereum-Bridge API, which is a log listener listens to the oraclize query from private chain and connect to oraclize service.
