That’s not what I knew. Mediator and Enterprise Gateway is for Runtime mediation and threat detection, but API portal is kind of web site for API information query for Design-time. So it doesn’t make sense if they could combined together. I think you may talk about API Gateway not API Portal.
API Gateway is a Runtime for API mediation (just like Mediator but also support REST, Mediator only support WS) and API policy enforcement (like threat detection, message transform, routing and so on). And API Gateway runs on IS as a package (but actually it has its own server), so its license comes with IS license (usually it’s a limited functional license for IS, because you won’t want to use that IS instance to integrate when you set it up as API Gateway).
