I don't recommend building your API with it unless your engineers' ops skills are on point. I'm currently contracting for an org that is transitioning from java & clojure services hosted in a colo backed by postgres to full on lambdas written in node backed by dynamoDB. They've built a very impressive Rube-Goldberg machine for taking some data from an etl process, inserting it in dynamo, and then retrieving when an endpoint is hit. In the meantime code quality and development speed have taken a nose-dive with a very important deadline looming in the near future. Lambdas are great for event-driven tasks and cronjobs though.
