Create a Rest API for use in external software

I would love to integrate your solution into an Unreal Engine plugin via restful API. I believe Eleven Labs (https://docs.elevenlabs.io/api-reference/quick-start/introduction) is an excellent of what I'm looking for. Having external tools is useful, but having the ability to use our games content to seed the lines you write, and then allow seamless importing of the lines we select would be ideal!
