IPQuery is a developer-focused API service that provides detailed information about IP addresses, including geolocation data, ISP details, and security-related insights such as VPN, proxy, and Tor detection. It is designed to be simple and accessible, allowing developers to integrate IP intelligence into applications using standard HTTP requests without requiring authentication or API keys.

The platform supports querying individual IPs or bulk requests (up to thousands of addresses in a single call), returning structured data in formats like JSON, XML, YAML, or plain text. It also includes risk scoring and flags to help identify potentially malicious traffic, making it useful for fraud detection and security analysis.

IPQuery is built to be lightweight and easy to adopt, with no SDKs required and compatibility across any programming language that can make HTTP requests. It emphasizes open access with a free tier, minimal setup, and no rate limits for typical use cases, positioning it as a straightforward alternative to more complex IP data services.

Key features include:

• IP geolocation data (country, city, region, timezone)
• ISP and ASN information lookup
• VPN, proxy, Tor, and risk detection flags
• Bulk IP queries (up to 10,000 per request)
• Multiple response formats (JSON, XML, YAML, text)
• No API key required with free access

Common use cases include enhancing security systems with IP risk detection, building geolocation-based features, analyzing user traffic, preventing fraud and abuse, and integrating IP lookup functionality into web or backend applications.
