TL;DR

• The upgraded WHOIS API runs real-time lookups with improved parsing accuracy.
• It’s now 2x faster than before. 
• Account rate limits now go up to 200 requests per second, up from 50.
• Control the cache freshness and choose the protocol used to retrieve domain registration data.
• Some changes may affect how you integrate.

TL;DR

• The Disposable Email Domains Database has been upgraded with a more precise machine learning detection model that reaches 99% tested detection precision.
• It adds scoring for every domain on a scale from 0 to 100, allowing you to set your own block, verify, and allow thresholds based on the score.
• It tracks 162,000+ disposable domains and is refreshed daily in CSV and JSON.

TL;DR

• You can now restrict API requests to a list of trusted IP addresses, so a leaked or shared key alone is no longer enough for unauthorized users to use your API key.
• Enterprise account administrators using Parent-Child API keys can see API usage broken down by individual team member or combined for the whole account.
• Both are available now in your account settings. The IP allowlist is off by default, and your account setup stays the same.

TL;DR

• The feed now captures up to 2x more newly added, updated, dropped, and discovered domains each day.
• Every domain comes with a more complete registration record, because the feed compares its RDAP and WHOIS data and keeps the fullest version.
• No actions needed on your side: the files and the way you integrate them stay the same.

WhoisXML API is pleased to announce the addition of support for two-factor authentication (2FA) — an important new security upgrade for user accounts.

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 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 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.
