+### Cursor-based Pagination
+
+Cursor-based pagination is supported on collection endpoints for entries and assets:
+
+```js
+const response = await client.getEntriesWithCursor({ limit: 10 })
+console.log(response.items) // Array of items
+console.log(response.pages?.next) // Cursor for next page
+```
+
+Use the value from `response.pages.next` to fetch the next page or `response.pages.prev` to fetch the previous page.
+
+```js
+const nextPageResponse = await client.getEntriesWithCursor({
+  limit: 10,
+  pageNext: response.pages?.next,
+})
+
+console.log(nextPageResponse.items) // Array of items
+console.log(nextPageResponse.pages?.next) // Cursor for next page
+console.log(nextPageResponse.pages?.prev) // Cursor for prev page
+```
