Change Log

26th July 2024

• API now running on 4 servers globally and all accessible at api.ipapi.is
• Hosting detection quality was improved substantially
• This API was systematically compared to some of the main competitors (ip-api.com, ipinfo.io, ipdata.co) in a blog article named An honest Comparison of ipapi.is to its Competitors

6th June 2024

• There were a lot of improvements in the past year, the changelog on ipapi.is/changelog.html is more actively updated
• The API has now very accurate VPN data from Systematic VPN Detection by Exit Node Enumeration
• The abuse object was added to the API output
• Geolocation improved significantly
• The abuser_score was added as described in ipapi.is/blog/abuser-score.html

3th August 2023

• The self-made geolocation database is available for download on the GitHub Repository
• Several data points were added to API:
• is_mobile flag that determines if the IP address belongs to a mobile provider
• continent in the location object that specifies the continent as 2 letter code
• added type to the company object
• I added a lot of hosting IP ranges to the API
• The asn and company type field (type) is much more accurate in the most recent version

2nd April 2023

• API is now running on 3 parallel clusters and can serve roughly 30 million request per day.
• For March 2023, the time was wrong for the fields local_time and local_time_unix (Mostly because of DST). This was fixed for good now.

IP Address API

This IP address API returns useful meta-information for IP addresses. For example, the API response includes the organization of the IP address, ASN information and geolocation intelligence and WHOIS data.

Furthermore, the API response allows to derive security information for each IP address, for example whether an IP address belongs to a hosting provider (is_datacenter), is a TOR exit node (is_tor), if an IP address is a proxy (is_proxy) or VPN (is_vpn) or belongs to an abuser (is_abuser).

This API strongly emphasizes hosting detection. A complicated hosting detection algorithm was developed to achieve a high detection rate. Thousands of different hosting providers are tracked. Whois records, public hosting IP ranges from hosting providers and a proprietary hosting discovery algorithm are used to decide whether an IP address belongs to a hosting provider or not.

Quickstart

Lookup any IP address: https://api.ipapi.is/?q=3.5.140.2

Lookup your own IP address: https://api.ipapi.is/

Usage with JavaScript:

fetch('https://api.ipapi.is/?q=23.236.48.55')
  .then(res => res.json())
  .then(res => console.log(res));

Usage with curl:

curl 'https://api.ipapi.is/?q=32.5.140.2'
