The Disposable Detector API checks whether an email address or domain belongs to a known disposable email service.
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:
  • Daily usage
  • Request speed
Exact thresholds are not disclosed for security purposes.
Typical client-side usage (such as signup validation) will not encounter these limits under normal conditions.
