Changelog v1

While version 1 of the API is marked as deprecated, we’ve introduced several important improvements to the tools available through this version. Below is a detailed overview of the latest enhancements.

🔧 Tool Improvements

DNS Checker

Our DNS checker has been completely reworked with a more reliable and faster resolution engine:

• Increased accuracy when retrieving A, AAAA, MX, CNAME, and TXT records.
• Improved error handling: clear reporting of issues like timeouts or invalid domains.
• Faster response times through caching and parallel resolutions.
• Added support for reverse DNS lookups.

Mail Checker

The email validation tool is now significantly more robust:

• Enhanced MX record checks to better detect if a domain actually supports email delivery.
• Catch-all detection: now able to recognize whether a domain accepts all email regardless of the local part.
• Improved syntax analysis in compliance with RFC 5322.
• New logic to detect disposable email addresses and known temporary mail providers.

Subdomain Finder

One of the most significant upgrades is the Subdomain Finder, now much more powerful:

• Complete subdomain enumeration: uses multiple sources and techniques (including DNS brute-force, certificate transparency logs, and passive databases).
• IP resolution: each discovered subdomain can now be resolved to its corresponding IP address.
• Returns ASN and geolocation data for resolved IPs when available.
• Wildcard detection and filtering to avoid false positives.
• Optimized for speed and scalability, even for domains with thousands of subdomains.
