We offer GeoIP2, minFraud, and proxy detection web services. Our web services are based on the HTTP protocol, and there are no databases nor software to install. We also offer a batch upload service where you can upload a text file containing IP addresses and get back a CSV file containing associated GeoIP2 data.
The queries do not expire. Our services have had 99.98% uptime since October 2002. We send out a warning email to purchase more queries when the number of queries remaining reaches 10,000. We send another email if you run out of queries.
