Check x-rate-limit-* response headers

[milh0use]

Check the response headers for guidance on request rates

x-rate-limit-limit: The number of times you can request the given endpoint within a certain number of minutes (otherwise known as a window).
x-rate-limit-remaining: The number of times you have left for a given endpoint within a window.
x-rate-limit-reset: The number of seconds left until the window resets.
For most endpoints, this is 15 requests per 15 minutes. So if you have set the global sleep_on_rate_limit to True, the process looks something like this:
api.GetListMembersPaged()
# GET /list/{id}/members.json?cursor=-1
# GET /list/{id}/members.json?cursor=2
# GET /list/{id}/members.json?cursor=3
# GET /list/{id}/members.json?cursor=4
# GET /list/{id}/members.json?cursor=5
# GET /list/{id}/members.json?cursor=6
# GET /list/{id}/members.json?cursor=7
# GET /list/{id}/members.json?cursor=8
# GET /list/{id}/members.json?cursor=9
# GET /list/{id}/members.json?cursor=10
# GET /list/{id}/members.json?cursor=11
# GET /list/{id}/members.json?cursor=12
# GET /list/{id}/members.json?cursor=13
# GET /list/{id}/members.json?cursor=14

# This last GET request returns a response where x-rate-limit-remaining
# is equal to 0, so the API sleeps for 15 minutes

# GET /list/{id}/members.json?cursor=15

# ... etc ...
