Yes, all of it! I have written about how to measure this uptime formally in the past…

API developers wrestle with myriad ways to manage errors and exceptions related to business logic, infrastructure (databases, other APIs), and unhandled concerns in an ad-hoc way, before constructing a response to a REST call.
