Some use cases can be: It’s hard to generate completely random data on the blockchain can be a problem, you could use Oraclize to get a random number from outside the blockchain. The oraclize-lib enables the use of the Provable engine capabilities also in a non-blockchain context, by providing an abstraction layer which resolves to Provable HTTP API. The oraclize-lib is currently in an experimental stage. I have read the Oraclize documentation: https://docs.oraclize.it/#home. and similar topic like: How do oracle services work under the hood. But is still have a question, take this example: I have a simple smart contract that makes a Oraclize call (or an API call) to a data source.
