+# {{ $frontmatter.title }}
+
+The `useInfiniteQuery` method allows you to use the original [useInfiniteQuery](https://tanstack.com/query/latest/docs/framework/react/guides/infinite-queries)
+
+- The result is the same as the original function.
+- The `queryKey` is `[method, path, params]`.
+- `data` and `error` are fully typed.
+- You can pass infinite query options as fourth parameter.
+
+::: tip
+You can find more information about `useInfiniteQuery` on the [@tanstack/react-query documentation](https://tanstack.com/query/latest/docs/framework/react/guides/infinite-queries).
+:::
+
+## Example
+
+::: code-group
+
+```tsx [src/app.tsx]
+import { $api } from "./api";
+const PostList = () => {
+  const { data, fetchNextPage, hasNextPage, isFetching } =
+    $api.useInfiniteQuery(
+      "get",
+      "/posts",
+      {
+        params: {
+          query: {
+            limit: 10,
+          },
+        },
+      },
+      {
+        getNextPageParam: (lastPage) => lastPage.nextPage,
+        initialPageParam: 0,
+      }
+    );
+
+  return (
+    <div>
+      {data?.pages.map((page, i) => (
+        <div key={i}>
+          {page.items.map((post) => (
+            <div key={post.id}>{post.title}</div>
+          ))}
+        </div>
+      ))}
+      {hasNextPage && (
+        <button onClick={() => fetchNextPage()} disabled={isFetching}>
+          {isFetching ? "Loading..." : "Load More"}
+        </button>
+      )}
+    </div>
+  );
+};
+
+export const App = () => {
+  return (
+    <ErrorBoundary fallbackRender={({ error }) => `Error: ${error.message}`}>
+      <MyComponent />
+    </ErrorBoundary>
+  );
+};
+```
+
+```ts [src/api.ts]
+import createFetchClient from "openapi-fetch";
+import createClient from "openapi-react-query";
+import type { paths } from "./my-openapi-3-schema"; // generated by openapi-typescript
+
+const fetchClient = createFetchClient<paths>({
+  baseUrl: "https://myapi.dev/v1/",
+});
+export const $api = createClient(fetchClient);
+```
+
+:::
+
+## Api
+
+```tsx
+const query = $api.useInfiniteQuery(
+  method,
+  path,
+  options,
+  infiniteQueryOptions,
+  queryClient
+);
+```
+
+**Arguments**
+
+- `method` **(required)**
+  - The HTTP method to use for the request.
+  - The method is used as key. See [Query Keys](https://tanstack.com/query/latest/docs/framework/react/guides/query-keys) for more information.
+- `path` **(required)**
+  - The pathname to use for the request.
+  - Must be an available path for the given method in your schema.
+  - The pathname is used as key. See [Query Keys](https://tanstack.com/query/latest/docs/framework/react/guides/query-keys) for more information.
+- `options`
+  - The fetch options to use for the request.
+  - Only required if the OpenApi schema requires parameters.
+  - The options `params` are used as key. See [Query Keys](https://tanstack.com/query/latest/docs/framework/react/guides/query-keys) for more information.
+- `infiniteQueryOptions`
+  - The original `useInfiniteQuery` options.
+  - [See more information](https://tanstack.com/query/latest/docs/framework/react/reference/useInfiniteQuery)
+- `queryClient`
+  - The original `queryClient` option.
+  - [See more information](https://tanstack.com/query/latest/docs/framework/react/reference/useInfiniteQuery)
