Calling an AI video API looks simple in a demo:
Send a prompt.
Wait for a response.
Show the video.
In production, the model rarely returns a video in the original HTTP request. It creates a remote job, gives you an external task ID, moves through provider-specific states, and eventually returns either a media URL or an error. Your application has to keep user state, billing state, moderation state, and provider state consistent while that happens.
