Inquiry About Creating Video with Audio and Background Image Only via API

Hello,

We are currently using the API to generate videos by combining an avatar and voice.

Additionally, we would like to create videos that contain only audio with a background image, without including an avatar. We noticed that this feature is available in the web service. However, according to the official documentation, we could not find a way to implement audio + background image video generation through the API.

Could you please let us know if there are any plans to support this feature via the API, or if there is any documentation or reference that we may have missed?

Thank you for your assistance.
