 The `ok` property throws for any other response. To handle those, switch over the `Output` cases, such as `.unauthorized` or `.undocumented(statusCode:_:)`.
 
+### Fetching More Pages
+
+Lists are paged. Pass a page's ``Components/Schemas/PagedDocumentLinks/nextCursor`` as the `cursor` of the next request:
+
+```swift
+var apps: [Components.Schemas.App] = []
+var cursor: String?
+
+repeat {
+    let page = try await client.appsGetCollection(query: .init(limit: 200, cursor: cursor)).ok.body.json
+    apps += page.data
+    cursor = page.links.nextCursor
+} while cursor != nil
+```
