Hello! Expansion in the Stripe API is explained here, and isn't specific to a particular endpoint: https://stripe.com/docs/api/expanding_objects
It's a way to tell the API you want parts of the response to contain more information than the default, or to include things that aren't included by default.
Pulling your screenshot into this thread:
In this specific case the expand parameter is telling the Stripe API to include the full Payment Method object instead of just the Payment Method ID in the response.
