Our Products
A WHOIS API gives developers programmatic access to domain registration records. Instead of manually querying registries, wrestling with rate limits, and parsing inconsistent plaintext output, you send a domain name and receive structured information about domain names, including registration date, expiry date, registrar information, owner details, and host name server information, available in both JSON and XML formats. Live WHOIS Lookup fetches data in real time from WHOIS servers and RDAP to ensure the freshest results on every request, with no database dependency.
Features
Unlike other WHOIS API providers, we combine multiple data sources, including WHOIS protocol data, RDAP, web scrapers, and proprietary feeds. This layered approach makes our data more reliable and comprehensive.
We collect data through the WHOIS protocol, the oldest and still one of the most effective methods for retrieving domain ownership details. Its priority varies depending on the registrar and TLD combination, so it is not always our primary source of our WHOIS API.
Our WHOIS API also retrieves data through RDAP, the modern protocol designed to replace the traditional WHOIS protocol. Since WHOIS and RDAP generally provide the same ownership details, we switch between them based on TLD support, registrar configuration, and availability.
WhoisFreaks has developed in-house scrapers to collect WHOIS records across a wide range of TLDs. These scrapers can solve CAPTCHAs in real time, enabling consistent and reliable data collection. They play a key role in expanding TLD coverage and strengthening our fallback mechanisms.
Our WHOIS data is also enriched with proprietary data feeds. Although these sources are limited in number, they add unique coverage, improve WHOIS data quality, and enhance threat correlation with domain ownership data.
