The client provides a convenient way to interact with the model API.
npm install @fal-ai/client@alpha @fal-ai/server-proxy@alphafal.realtime.open is currently available on the alpha release and may change in a minor version.
Keep FAL_KEY on your server and expose an authenticated proxy route to your browser. For a Next.js App Router application, create app/api/fal/proxy/route.ts:
import { route } from "@fal-ai/server-proxy/nextjs";
export const { GET, POST, PUT } = route;Set FAL_KEY in the server environment, and protect this route with your application's authentication before deploying it.
The browser connects through your server proxy, which reads FAL_KEY from the server environment. Never put that key in browser code.
When running code on the client-side (e.g. in a browser, mobile app or GUI applications), make sure to not expose your FAL_KEY. Instead, use a server-side proxy to make requests to the API. For more information, check out our server-side integration guide.
