Ask HN: What REST APIs, in your opinion, deserve an award?

What REST APIs, in your opinion, deserve an award for an admirable quality, be it design, documentation, etc. For example, I would given an award for documentation to Stripe's API docs (https://ift.tt/O6V8V7) due to its simplicity and support for their official SDKs. The more general form of this question is: what are your favorite REST APIs and why?
