Currently, its primary goal is to simplify flow composition In Mist or any other environment, you need to download the file at dev.oraclize.it/api.sol. I don't think Mist supports importing files, but you can use the browser compiler, just paste your code into one pane, the Oraclize code into another, rename the tabs and import by name. Finally, verifying the signature of the AWS oracle is a comparatively "cheap" computational operation, so Oraclize's "honesty proofs" could potentially be verified on chain provided that the TLSnotarised content is short enough (like an API call). If your user account already has an API signing key, create the ~/.oci directory if it doesn't exist, and then go straight to 2. Create a Profile in the Oracle Cloud Infrastructure CLI Configuration File.

As a note, I downvoted due to some incorrect points. Namely the fact about not returning unused gas, Oraclize offers off-chain payments to high-volume clients to pre-pay for queries in fiat and only get charged for the amount of gas used + oraclize fees. The API allows you to request data that meets the specified filter criteria, and to group that data by the dimension of your choosing. The Usage API is used by the Cost Analysis tool in the Console.

Oraclize offers a number of services to developers. Oraclize works as a data carrier for decentralized apps. Developers can take advantage of this data carrier platform to build decentralized apps – including everything from online games to travel insurance DApps. 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.
