Though this is an approach worth considering for a bunch of local services, at least a subset of them, I don't see it working with 3rd party APIs. Consider something like Stripe — it is probably far more straightforward to invoke some HTTP endpoints, than to set up a huge infrastructure with millions persistent client connections.

Agreed. I believe that AMQP connections are best suited for wide and articulated local environments. Moreover REST HTTP endpoints are today's esperanto :)
