 ### Making API Calls
 
-The `Client` conforms to `APIProtocol`, which defines a method for every endpoint in the App Store Connect API. Each method accepts an `Input` value and returns an `Output` value with the response.
+Each endpoint is a method on `Client`, declared by `APIProtocol`. It returns an `Output` enum with a case for each documented response:
 
 ```swift
-let response = try await client.appsGetCollection(.init())
+let response = try await client.appsGetCollection(query: .init(limit: 10))
+let apps = try response.ok.body.json.data
 ```
 
+The `ok` property throws for any other response. To handle those, switch over the `Output` cases, such as `.unauthorized` or `.undocumented(statusCode:_:)`.
