Proweblook IP Checker

About Proweblook IP Checker

Proweblook IP Checker is an IP geolocation API that returns country, city, region, postal code, latitude/longitude, continent, timezone, currency, and calling code for a given IP address, along with ASN, AS name, AS organization, ISP, and network range. It also returns normalized risk signals, including proxy, VPN, Tor, and hosting flags, for use in fraud checks and traffic review. The API runs on Cloudflare's edge network, answering requests from the data center nearest the user rather than a distant origin server, with a median response time of about 5ms across 330+ edge locations in 100+ countries.

The service is accessed via a root endpoint, a "/v1/ip" path, or a legacy path, returning JSON responses with fields such as status, ip, country, city, asn, as_name, isp, network, timezone, is_vpn, and response_ms. It supports both IPv4 and IPv6 lookups. It is intended for developers building applications that need geographic personalization (using timezone, currency, country code, and calling code), network/ownership lookups, or fraud and risk screening based on IP characteristics.

The product offers 20,000 free checks per month, and a paid plan listed at $4.99 for unlimited API access. A browser-based lookup tool and an API playground are available for testing without an API key or credit card, alongside documentation, an OpenAPI 3.0 specification, and a Postman collection for integration.
