An ipapi.is alternative that tells proxies apart

ipapi.is is cheaper and answers every field on every plan, its free one included. Its is_proxy covers open proxies, and its docs say residential and mobile proxies mostly go unflagged. InternetData flags residential, mobile, datacenter and public proxies apart, with the pool and when we saw it.

The free fields need no key and have no cap. A free account's first 100 lookups each day answer every field.
