This endpoint is free to use and can be called directly from client-side applications thanks to full CORS support.

What this API Helps With

  • Detecting disposable or temporary email addresses
  • Improving email list quality
  • Reducing bounce rates and spam-related risks
  • Increasing the accuracy of user registrations and submissions
This makes the API valuable for developers integrating signup validation, marketers maintaining clean lists, or any workflow where email quality matters.

Rate Limiting

The free Disposable Detector API includes rate limits on:
