What does antideo do?

antideo is an API service that helps developers and businesses validate user data and prevent spam. It provides three core services: IP reputation checking, email address validation, and phone number verification. The service checks IP addresses against known spammer databases, validates email addresses to detect disposable or invalid domains, and verifies phone numbers across international formats.

The service operates through a straightforward REST API that returns structured JSON responses. It processes over 240,000 API calls daily and maintains databases of more than 50,000 disposable email domains and 2,000+ free email providers. antideo offers a free tier with 10 API calls per hour, plus paid plans with higher rate limits starting at $5 per month.

This tool is particularly useful for web applications that handle user registrations, contact forms, or lead generation. Developers can integrate antideo's API to filter out fake signups, reduce spam submissions, and maintain cleaner customer databases. Businesses using these validation services can protect their domain reputation and focus resources on legitimate customer inquiries.
