Summary

It is possible to encounter several HTTP errors when using the Overpass API, relating to the status of a user's queries. For experienced users, helpful information is available regarding these errors from /api/status. The ability to catch and access the information from /api/status would be beneficial to users trying to make a significant number of queries while respecting the rules of the Overpass servers.

Expected results

Something like the following would be expected:

query_string = ('way["highway"~"."](around:20,{},{},);out;').format(lat, lon)
    while True:
        try:
            result = api.query(query_string)
            break
        except (overpy.exception.AnyOverpassError):
            print(result.api_status)

Which gives some output:

'Connected as: 2557965506
Current time: 2017-05-01T16:17:38Z
Rate limit: 2
2 slots available now.
Currently running queries (pid, space limit, time limit, start time):'

As found on the /api/status site.

This would allow users to see information like rate limit and available slots, and adjust the code to respect the status of the server.
