Technical Documentation

What this API does

The Email Validator API is designed to help developers verify the authenticity and deliverability of email addresses through comprehensive checks. It includes syntax validation, MX record lookup, SMTP verification, and the detection of disposable, role-based, or catch-all emails. This capability aids in maintaining high-quality email lists and enhancing communication reliability.

How it works

Developers can implement the API by sending simple GET or POST requests to the endpoints. The API processes the provided email addresses and performs the necessary checks before returning the results. The output can be formatted in JSON or XML, allowing for straightforward integration with various programming environments.

Authentication

The Email Validator API requires authentication via an API key. Developers must sign up on the official website to receive their unique API key, which should be included in the request headers or parameters for successful validation.

Example usage

  • /validate?email=test@example.com - Validates the specified email address.
  • /validate?email=test@example.com&format=json - Returns validation results in JSON format.
  • /validate?email=test@example.com&format=xml - Returns validation results in XML format.

Limits

Developers can use the Email Validator API for up to 100 free validations per month. For higher usage, a subscription plan may be required, but detailed information on paid plans is not specified.

Ideal use cases

  • Integrating email validation into registration forms to ensure valid email entries.
  • Enhancing email marketing efforts by cleaning up email lists.
  • Improving user communication by verifying email addresses before sending important information.
