> Authenticate every request with your API key in the `X-API-Key` header or `Authorization: Bearer`. Keys start with `sk-nunchux-`.
> Image generation is synchronous: the image is in the response.
> Video generation is asynchronous: submit the job, poll its task until it reaches a terminal status, then download the output promptly, because output URLs expire.
