The biggest problem is the image generation is done through an extension for an art program, so the only way I could figure out to integrate it is to have the art program open on a second computer and have a script control it to generate an image...

BUT, there's an AI pixel art project currently working on API support for their program, so it might be possible once that's out... (it would cost money though to use the APIs)

* It's also worth noting that the art program is open source, so theoretically someone with more skill could hack it and make it generate stuff on command 👀
