What is freegeoip.io?
Freegeoip.io is a public HTTP API service designed for software developers to retrieve geolocation information for IP addresses. It offers a database that associates IP addresses with cities, providing additional details such as country, region, zip code, latitude, longitude, metro code, and time zone. The service supports multiple data formats including CSV, XML, JSON, and JSONP, making it versatile for integration into various applications.
Users can perform up to 10,000 queries per hour under the free tier, with requests exceeding this limit resulting in HTTP 403 errors until the quota resets. The web server is open source, allowing developers to download and run their own instances if the public service limits are insufficient. The service is community-funded and relies on GeoLite2 data from MaxMind for accurate geolocation information.
