I keep hoping one of these clients will add IPython/Jupyter style notebook specifically for REST calls.
I would love to produce a tutorial that has well formatted URLs with params, bodies, headers and pre-saved results that could also be rerun against local server.
I think you should be able to get pretty far by just writing Python code that uses the API; using requests that should be as readable as anything else?
Which brings me to: I just use Python snippets if I want to test a REST API quickly. What am I missing out of by not using these tools?
If I am writing a tutorial using REST calls, wrapping them in Python syntax is less than effective as a presentation. It also requires Jupiter backend running, which could be a burden to host for a popular multi-user tutorial.
It is something that O'Reilly is experimenting right now with their interactive tutorials, but even for them, it is early days.
