WHOIS API, Inc, doing business under the brand WhoisXML API, is a cyber intelligence provider specializing in domain, IP, and DNS datasets. The company also provides specialized Internet intelligence sources and services, such as predictive threat intelligence, website categorization, IP geolocation, and email verification.

WhoisXML API has been an Inc. 5000 honoree from 2017 to 2019 and 2021 to 2023 ^[1] and has offered its services to more than 52,000 users. Its clients include Fortune 500 companies, security and technology solutions providers, and governmental organizations.

WhoisXML API has extensive domain and DNS data coverage in the market. As of 1 September 2023, its repositories cover more than 16.7 billion WHOIS records and 99.5% of all the IP addresses in use.^[2] The company has partnered and continues to collaborate with large data aggregators worldwide, including domain registries, registrars, ISPs, and security agencies.

History and Growth

WhoisXML API was incorporated in 2014. However, it was initially conceptualized in 2010 when its CEO and founder Jonathan Zhang worked on a network security project that required access to structured WHOIS data.^[3] Zhang’s struggle to find a unified and readily integrable data source led to the idea of creating a company that would help organizations with that business problem.

WhoisXML API’s overarching goal is to make the Internet safer and more transparent. The company does that by providing comprehensive and in-depth cyber intelligence.

Products and Services

WhoisXML API offers several products and services through various consumption models—APIs, data feeds, and web-based GUIs. Below is a list of the products WhoisXML API offers as of 1 September 2023.

DNS Database Coverage

In the second quarter of 2023, WhoisXML API released Premium DNS Database, a market-leading passive DNS repository that the company claims has the highest number of fully qualified domain names (FQDNs).^[4]

Cyber Threat Intelligence

WhoisXML API supplies a wide range of Threat Intelligence APIs that users can analyze and integrate into existing security solutions. These APIs include:

Domain Infrastructure Analysis API
SSL Certificates Chain API
SSL Configuration Analysis API
Domain Malware Check API
Connected Domains API
Domain Reputation Scoring API

The company also offers Threat Intelligence Data Feeds that list malicious Internet assets involved in phishing, botnets, malware, C&C servers, spam, Tor exit nodes, and other cyber attacks and suspicious web activities.

Domain Research Suite (DRS)

WhoisXML API has a web-based domain search and monitor platform called the “Domain Research Suite (DRS).” DRS is a 9-in-1 solution designed to look up a domain’s current and historical WHOIS details, pivot off any WHOIS record to find connected properties, and search for domains or subdomains containing specific text strings. The suite also allows users to monitor domain registration activities. It is composed of the following tools:

Reverse WHOIS Search
WHOIS History Search
WHOIS Search
Reverse DNS Search
Domain Availability Check
Domains & Subdomains Discovery
Domain Monitor
Registrant Monitor
Brand Monitor

IP Intelligence

In 2022, WhoisXML API launched the Regulatory Compliance IP Geolocation Data Feeds, which currently contains IP addresses and netblocks owned by entities based in locations restricted by the Office of Foreign Assets Control (OFAC). The company is planning to provide separate files specific to areas restricted by the International Traffic in Arms Regulations (ITAR) and the Common Foreign and Security Policy (CFSP).^[5]

Partnerships and Collaborations

WhoisXML API has worked with prestigious entities in the cybersecurity, fraud detection, brand protection, and law enforcement sectors. In April 2022, the company was invited to present at Europol’s 13th Operation In Our Sites (IOS) held in Alicante, Spain.^[6]

In 2020, WhoisXML API worked with a Bloomberg columnist to raise awareness about coronavirus-themed domains^[7] that were likely to figure in malicious activities. Its other collaborations include those with the National Child Protection Task Force (NCPTF),^[8] ScamAdviser,^[9] and EU DisinfoLab.^[10] WhoisXML API also became a member of the Business Constituency^[11] in 2023.

WhoisXML API continues its call for partnerships under several programs, namely:

Affiliate Programs
Data Exchange Program for Internet Abuse Prevention
Security Intel Exchange Program
Research and Media Collaborations
