[portland] Creating an API with Metered Billing

[Jeff Schwaber]

That's super interesting!

I haven't done usage limits, but I've played with the throttling stuff of
Django Rest Framework:
http://www.django-rest-framework.org/api-guide/throttling/ and you could
definitely put usage counting in there. Once you've got usage counting,
limits seem like a simple step inside that framework.

The big challenge is going to be that, naively, now all of your API
requests are database updates, and from a scalability point of view, that
sucks. Of course you could make them logging statements instead and then
have a background process reading the log to generate the current counts,
but then you'll be behind a bit, so users may bounce over the limits a bit.
