First Watch Detection Precision Now Exceeds 98%, Further Cutting False Positives by 45%

WhoisXML API is proud to announce that the false positive rate of its First Watch Malicious Domains Data Feed went down from 3% to 1.66%. This significant reduction in false alarms translates directly into a more efficient, reliable, and trustworthy predictive threat intelligence solution for users, allowing them to block upcoming threats with higher confidence and fewer interruptions.

WhoisXML API Introduces Domain Info API — A Modern Way to Access WHOIS Data

WhoisXML API announces the launch of the Domain Info API, a new cyber intelligence solution designed to deliver a single, enriched WHOIS record for any active or expired domain name by leveraging WhoisXML API’s massive historical WHOIS database. The Domain Info API automatically fills in WHOIS fields that are redacted or missing for any domain name, using the latest available historical data.

WhoisXML API Launches the TLD RDAP Monitor

WhoisXML API is proud to announce the launch of the TLD RDAP Monitor, an intuitive dashboard that constantly monitors the range of adoption of the Registration Data Access Protocol (RDAP) across 1,440 top-level domains (TLDs).

The TLD RDAP Monitor answers a critical need within the domain data ecosystem. As the industry transitions to RDAP, TLD registries have implemented the new protocol with varying degrees of progress, with some slower than others. This lack of uniformity can lead to data retrieval errors and application failures for those who rely on domain data access for their products and services.

WhoisXML API Launches an MCP Server to Enable LLM Access to Internet Infrastructure Intelligence

WhoisXML API announces the launch of its MCP server that allows large language models (LLMs) to query 17 of its APIs, enabling users to access unique internet infrastructure intelligence data, run bulk queries and conduct complex internet infrastructure research projects directly from the chatbot interface using natural language.

The MCP server is software that enables the use of the Model Context Protocol, an open standard that enables LLMs and other AI systems to securely connect to external data sources. The protocol uses a client-server architecture, where the client is the AI application that connects to the MCP server.

RDAP Readiness Enhanced with New Protocol Selector for WHOIS Lookup and DRS

We are excited to announce that a protocol selector has been added to WHOIS Lookup and WHOIS Search (on Domain Research Suite), giving users more flexibility to choose how to retrieve domain registration data. 

With this new feature, users can select from three protocols—RDAP, WHOIS, and Auto.

Upgraded Web Interfaces for All Lookup Tools

We’re excited to introduce upgraded web tool interfaces with enhanced data access across all our lookup tools. The improved GUIs are designed to make your lookup reports richer and simpler to use for investigations and testing, improving how technical and nontechnical users access and utilize domain, DNS, IP, and other cyber data accessible through this complete list of our lookup tools.

Here are the new features available to all logged-in users with credits.

Subdomain Database Coverage Expands from 2.3B to 9.6B Subdomains

In line with our commitment to continuous improvement, we recently expanded the data coverage of Subdomains Database Download from an average of 2.3 billion to more than 9.6 billion subdomain records, as seen in our latest weekly full files. This coverage enhancement is a direct result of techniques employed to optimize data processing and storage efficiency, with our development team focusing on improving data indexing and retrieval, as well as enhancing resolving processes—overall enabling faster lookups and more accurate results for our database.
