A free IP Geolocation and proxy/tor/VPN detection API.
IPQuery is an IP intelligence API that returns data for a given IP address, including location details (country, city, state, zipcode, timezone), ISP information, and risk scoring. Risk data covers whether an address is associated with mobile networks, VPNs, Tor exit nodes, or public proxies, along with a 0-100 score indicating likelihood of malicious activity. The API is accessed over HTTP at api.ipquery.io and supports JSON, XML, YAML, and plain text response formats.
The service supports single-IP lookups, a bulk endpoint accepting comma-separated IPs (up to 10,000 per request, returned in order), and an endpoint that returns the caller's own IP address. No API key is required, and there is a free tier with no stated usage restriction. Data is described as aggregated and processed on the provider's own infrastructure rather than through third-party resolvers.
It is suited to developers needing to integrate IP geolocation and risk/fraud-signal data directly via HTTP calls without an SDK. The provider states the API can be used in commercial applications, SaaS products, and internal tools, and that query data is logged only transiently for caching and abuse prevention rather than sold to third parties.
