If your smart contract needs to consume data from the outside world, you can use an oracle.

Learn about zkOracles in this video:

In this tutorial, we’ll build an oracle that retrieves data from a REST API. We’ll also write a smart contract that consumes information from this oracle.

Specifically, our oracle will retrieve data from a REST API that provides mock credit score information for two users–one with a high credit score and one with a low credit score. Our smart contract will consume this information and allow the user to prove their credit score is above a certain threshold (e.g. >700).
