Is there a way to access the suggested prompts through API or Unreal plugin?
Hello @nathan,
Welcome to the Convai Developer Forum!
You’ll need to use the Generate Conversation Options feature, which is detailed in our documentation:

Please note that this feature requires a Professional plan or higher to access.
Let us know if you have any further questions or need assistance setting it up! 
Hey that’s really neat and a pretty new feature I think? Very cool.
