Collect the query, call your backend to keep the API key safe, the backend calls GPT with a prompt to return movie names, parses the response, looks up the movies on a real API, and the frontend displays the results with loading, error, and empty states.
To keep the API key safe. Calling the AI directly from React exposes the key to anyone. A backend or serverless function holds the key and calls the AI, so the key never reaches the browser where it can be stolen.
It sends a prompt that instructs GPT to return movie names in a parseable format, parses the response into an array of names, then looks up each name on a movie API like TMDB to get the real movie data, and returns that to the frontend.
