FreeIPAPI is an IP geolocation API for developers, supporting IPv4/IPv6 lookups and returning information such as country, city, region, coordinates, time zone, and currency in JSON or XML. Its positioning goes beyond simply “looking up an IP location”: it also includes country data, calling codes, time zones, languages, IP distance calculation, proxy/VPN/hosting detection, and batch lookups for up to 50 IPs. It is suitable for website personalization, internationalization, risk control, and data analysis.
Based on the available content, the API supports both GET and POST requests. The IP can be passed via the path, query parameters, or request body; if no IP is provided, it uses the source IP of the request. Examples are provided for PHP, Curl, Python, Java, Node.js, jQuery, Go, Ruby, C#, and Rust, suggesting a relatively low integration barrier. The documentation includes sections such as Get Started, API Keys, whitelisting, subscriptions, and API Reference, and the feature documentation appears fairly complete. Paid features include API Keys, IP/domain whitelisting, batch lookups, and email support. There is also a browser extension for quickly checking local IP information.
The documentation describes it as a free and open-source IP geolocation API, but the crawled content does not provide a code repository, license, or deployment guide. As such, we can only confirm that it claims to be open source, but cannot assess the extent of its openness. Self-hosting support is also not clearly stated; the Enterprise plan’s custom server locations appear more like managed-service location customization. In terms of pricing, the free plan is €0/month, requires no account, allows 60 requests/min, permits commercial use, and includes TLS/SSL, but servers are Europe-only. The Unlimited plan costs €9.90/month or €99/year, claims unlimited requests and global servers, and provides more management and support features. The Enterprise plan uses custom pricing and includes an SLA, custom invoicing, dedicated support, and more.
The main advantages are that it is free for commercial use, requires no registration to get started, has a simple API design, and covers a broad range of supporting data, making it suitable for rapid development and small to medium-traffic projects. The drawbacks are that the free plan has a clear rate limit and only European servers; the content does not disclose geolocation accuracy, details of underlying data sources, error codes, compliance and privacy information, or access and payment options for mainland China. It is a good fit for developers who need lightweight IP geolocation, internationalization fields, time zone/calling code data, and basic anti-proxy detection. Teams with strict requirements for high accuracy, strong SLAs, private deployment, or low latency in China should conduct further validation or consider alternatives such as MaxMind, ipinfo.io, ipapi.co, IP2Location, or domestic cloud providers.
The crawled content does not provide information about mainland China nodes, ICP filing, payment methods, or availability, so access from China is unknown. If using it in a production environment in China, we recommend testing DNS resolution, latency, stability, and payment feasibility, and preparing local caching or a backup API.
